The 2nd biggest religion in each state (US)

Fascinating!

If atheism was included, it'd be the biggest along a variety of states

This is clearly counting Mormons as Christians here, despite their significant divergence

Probably because that "significant divergence" isn't enough to make them not Christians. Joseph Smith's bible fanfic might be as ridiculous and idiotic as he was but that's not enough to distinguish it from the previous iterations.
- Not really. It's basically as divergent as islam. Mormonism isn't even monotheist.
- Usually adding a new prophet gets you a separate category, in abrahamic religions.
No, they're True Christians.
- Not sure why you got downvoted... They believe they are.
  Of course every religion believes they are the "true" ones.

Is Mormonism considered a form of Christianity here? Even with the stuff about planets?

That’s a nice slippery road Christians really do not want to travel down.
Baptists dislike Catholics. So of course they have a problem with Mormons. Just like they all have a problem with all other religions. Of the three brands I just named the Catholics are to me the most tolerant of others. Not that they are that tolerant. Mormans hide their intolerance with some fake happy smile but they are still just as intolerant. Especially to their own people.
Jesus, the Mormons change their doctrine all the time, just like mainstream ‘Christians’. They have even backed away from the ‘stuff about planets’ in recent years. They want so badly to be bland.
- Christians don't change their doctrine.
- I'm curious what doctrine you think has been changed? I'm a member of the church and can happily answer questions to the best of my ability.
  I will agree that policy has changed over time (for better and for worse, it's run by a bunch of regular people and people make both good and bad decisions) but the core doctrine is pretty static.
It's Christianity+.
The plus is just extra craziness.
Momos would say yes (a recent change), most Christians would shrug, some Christians would be offended that you would suggest it and say that mormonism is a heresy.
- The ones who shrug probably don't know what mormonism is. Anytime I've told a Christian who didn't know, their immediate reaction was "WTF"
- Protestants say that about Catholics, they are both still Christian
- So glad everyone is on the same page /s
Yeah, we're pretty generous about what counts. I'd argue most evangelicals aren't sincerely Christian either but whatever.
- Wouldn't say "most", but a sizable portion. Same can be said about Roman Catholics.
- I mean, if they believe Jesus was *Christ then that makes them christian yes?
- I mean have you seen the Midwest?
I group Abrahamic religions thusly: Judaism, Christianity, Mormon, Jehovahs Witness, Scientology. But as murderface put it about religion: "It's all the same shit!"
- Wait, Scientology? Scientology isn't Christian at all... is it? I thought it was sci-fi nonsense?
- Somebody shoulds tells Murderface that it's not alsways-ways abouts him.
I don't know about here on Lemmy in particular but I looked it up and found a 2011 Pew poll that gives some statistics: "Mormons perceive hostility directed toward them from evangelical Christians. Fully half of those surveyed (50%) say that evangelical Christians are generally unfriendly toward Mormons, compared with 21% who think evangelicals are neutral toward Mormons and 18% who say evangelicals are friendly toward Mormonism. Pew Research Center surveys show that roughly half of white evangelicals (47%) say that Mormonism is not a Christian religion, and two-thirds of evangelicals (66%) say that Mormonism and their own religion are very or somewhat different." It also says that "one-third of non-Mormon U.S. adults (32%) say the Mormon faith is not a Christian religion, and an additional 17% are unsure whether Mormonism is Christian."
- They literally believe in multiple gods, though. At least Roman Catholics and Protestants worship the same God.

I had no idea we have so many Buddhists!

We don't really. The largest group is obviously Christian. The second largest group in every state is those with no religion, but they are ignored here. And the remaining 1-13 percent is split among a number of minority groups, meaning that the second largest religion in each state is only about <1-6 percent of the population.
- The second largest group in every state is those with no religion
  How do you count that. I know a lot of people who will call themselves Christian if asked - but they never do anything to show it. They are never seen in Church (not even Christmas), only know the parts of the bible everybody knows because they are common (a couple of the 10 commandments, "The Lord is my Shepard, I shall not want", Jesus had 12 disciples). Last I checked about 40% of the US attends a christian church, but it appears to me like the majority of the rest of not no religion, but just don't bother practicing their claimed religion. (though it isn't clear how their kids will end up) You can thus count them either way.
- Are Christians and catholics counted as the same religion?

I actually would have guessed Islam for Utah

Utah stands out on this to me. This map conflates all denominations of shared religions, and Utah is notably 50% Mormon and 13% other Christian denominations. Since some denominations of a shared religion are significantly different from each other and can shape the cultural landscape, it seems like part of the picture is missing with just the information shown.

I think it would also be helpful if this map also noted which states had a second most common religion at more than 1% or so of the population.

Mormons are Christians in the same way Baptists and Catholics are both Christians. It's not different enough to be considered a whole new religion.

We have such a wide variety of cults to choose from.

Pick one so you can hate the rest!
Misding the democrats and republicans cults

Results are pretty encouraging if you broaden the question slightly to include people who aren't religious. There are probably people out there who might draw an incorrect conclusion from the map posted here and think that these colors represent the views of the second largest group of people (some of whom may vote) in those states.

They're conveniently skipping past 20 to 30 percent of the population to show the ~1-2% and smaller fractions.

Yeah this is an almost completely bogus map. Pew research has tracked ‘Nones’ for years and it is the fastest growing ‘religion’ by far nationwide.
- Obligatory "absence of religion is not a religion" in case passersby miss the meaning of your second set of "'" but yep.

So, basically all Abrahamic Religions, except Buddhism.

I think even Utah and Arizona would have mormonism as #2, which is abrahamic
You think Hinduism is Abrahamic?
- No, I forgot about that one state.

South Carolina and Arizona out here like, "we built different"

Aye don't leave out sneaky Delaware
- I did not see sneaky Delaware. Thank you. 😁

Whenever I see these statistics, I wonder something quite the opposite: I wonder which religions or belief systems are the smallest (as in, which religions or belief systems are the ones with the fewest to almost no followers at all).

Problem is: polls and surveys often ask one's religion from a limited, predetermined list. The person often can't even write down the name of their religion (or whatever label that closely describes it), so we end up not seeing statistics about non-mainstream religions such as Neo-Hellenism, Neo-Sumerian, Gnosticism, Thelema, among many others... Many end up picking "Non-religious" while they do practice a religion.

Then, there's the Internet, said to connect people with other people, often tossing Hapax Legomena (words that only happen once across the entire dataset, e.g. "Lilith" only appears once across the entire bible so Her name is a biblical Hapax Legomenon) into the oblivion (to be fair, it's just a byproduct of Zipf's Law so the Internet isn't really to be blamed), so we don't get to know about very unique (and likely very deep and rich) belief systems that exist out there.

Even when there's only one individual following some belief system they built themselves, it'd be really interesting to know about it.

DC is not a state.
