Too harsh?

America just minimized this notice and keep it in the background ..... along with a dozen other notices ... and they keep wondering why their system runs so slow and keeps freezing up every once in a while

There's no minimize on this popup...
...so its just tucked away off screen with just a couple pixels still showing justttttt in case we want to bring it back to the forefront LMAO

Not too harsh, but it does play right into the hand of the oligarchs. The thinking that this is some zero sum game where you can win by being morally superior further drives a wedge between common people for the benefit of those in power.

You are doing exactly what they want you to be doing, digging in your heels and announcing that you will never respect people who have different opinions than you. Opinions which the oligarchs spend billions to put into people's heads.

I vehemently disagree that this is a matter of differing opinions.

Logic doesn't work this way: My knowledge of Great War history is limited to a dozen anecdotes, but this fact doesn't invalidate my knowledge of the C++ programming language.

More correct version of your sentiment: "I don't like your opinion about A, so I will ignore your opinion on any other theme ". Which is rather widespread and overall effective approach, though.

Yeah, but if I know someone’s a nazi, I’ll just ask someone else.
Sure, it's a logical fallacy, but I don't believe this binary is wholly true. A moral failure in any area indicates a likelihood for moral failures elsewhere. This likelihood is not irrefutable evidence, but it is not in any way illogical, either. It's basic pattern recognition. If you murder once, there is an increased likelihood to murder again. If you do drugs once, there is an increased likelihood to do drugs again. This is statistically proven.
It's like a corrupted database. Sure, the other data may not be corrupted, but now that there's proven corruption how am I to know what other data is or is not corrupted? Easier to just restore from backup and move on (in this case your backup is anyone else who is not a fascist).
Of course, I'd probably take Ben Carson's advice on brain surgery regardless, but that's because he has undisputed experience in a high skilled field. If he'd been diagnosed with dementia, that does not provide irrefutable evidence against his advice, but I'd probably seek a another opinion. If my GP was fascist, I'd prefer to get recommendations from a different GP.
Its not "opinion" its "cultish loyalty and devotion"
The world isn't logical. Knowledge of one topic is often applied to other topics.
If I had to hire a C++ programmer, and there were two candidates who were tied for the position except that one of them knew everything about the Great War, you can bet I'd hire him instead of the other. Not because I need anything at all related to the Great War, but it'd be nice if the person is able to relate the programming to something.
The Great War was an unforeseen consequence of many smaller locally logical events, almost like functions in code.
The programmer ought to be able to identify the Archduke Franz Ferdinand in the code, so that the entire system doesn't break down from killing one small insignificant process.
- The world isn't logical.
  The world IS logical. Fascists are fascist because of racism, propaganda, narcissism — a multitude of causes that made them fascist. Insane people are insane due to something that made/makes them insane. There is logic in their reasons for being illogical.
  An indication of poor logic somewhere is an indication of poor logic elsewhere, and it's a spectrum. There's a gargantuan chasm between someone mixing up dates vs being a flat earther. One indicates a singular momentary lapse in logic, which is common. The other indicates widespread corruption in logic; numerous logical failures, across a large range of time, and is reserved for people with extreme mental illness.

Nothing is too harsh at this point. Let er rip

I want to reply to random people on Facebook with this but don't want to risk my account

I'm only still using the site to stay in contact with family members

I am going to! I have taken the risk and starting sharing all the wonderful things I find here. If my family doesn't like it, well, I guess I now know them better. They can always block me and make get togethers awkward.
I was raised "born again christian" and had the Bible shoved down my throat my entire growing life. Those family members last voted for Trump. My turn to shove morality down their throats. I have been thinking that when we gather for the holidays this year that I am going to sit them all down for the "I'm concerned for you and the state of your soul" talk they all loved giving anytime I made any personal choices while growing up.
I have also been sharing things to troll different hate groups on there. ...Is trolling bad when it's done to pedophile worshiping fascist biggots?

They hate the left more than they hate kids.

That's not always true. Some of them love kids. Just, perhaps, not in the morally and legally acceptable way.
