Yeah I'm sure I've hear the figure of 10% as the "expected" level based on studies looking at animals other than humans. At least it means we seem to be approaching a time when people don't feel the need to hide it, which has to be a positive step.
And everybody should support it. I'm a straight man. I most certainly wouldn't want a female partner who was with me solely because she needs to show as straight when she isn't. That's patently unfair to everybody.
Love who you want to love without regret or shame.
Gay/bi/trans/queer/whatever neighbors, coworkers, friends, authority figures, whatever. That has absolutely fuck all nothing effect on me.
I'll like or dislike any given person on their character, not how they enjoy getting their nether regions tickled. And to that, I'll add that I've known some gay people who can absolutely go pound sand. That's based solely on shitty behavior as it would be with anybody. It is entirely unrelated to orientation.
Edit: I like Lemmy because I find myself seeing communities such as this one that wouldn't have shown up on Reddit. To me, it encourages communication among people in different demographics, and if I say something egregiously ignorant, it gives me opportunity to learn and grow.
We likely will never know the "actual" numbers because it's a moving target.
Homosexuality is thought to be linked to higher fecundity of all the female relatives. As birth rates decline, a slightly higher fecundity will drive an increase in observed homosexuality/bisexuality as a percentage of the population.
I'm sorry, I don't know how to handle links for that site. You may contact my maintainer, @rikudou@lemmings.world, if you wish to add it to supported sites!
