This just seems way too close ot being a troll. If I’m wrong, please do your research before posting here, this has been discussed to death over and over.

You’re not racist but you do come out as bigoted.

Get a life, troll and grow up.

If this is a genuine question, and not a halfhearted attempt at trolling, you need to be more specific about what you’re asking:

Are you looking for biological / evolutionary theories about why maaaaany animals show same sex sexual activity?

Are you looking for an anthropology/historical analysis of how human sexuality has been expressed in different ways and had very different norms and taboos than our current blend?

Or are you asking individuals to talk about their own experience and what lead them to identify as whatever?

Ask yourself the question why people “become” tall, small, blonde, blue eyed, have a certain ethnicity, …

They dont become! They are! (I am mostly gonna use gay as an example but the same applies to all lgbtq+ people in the same way)

The reason it seems like people “become” gay is because sexuality is something that develops during puberty. The same way tall people don’t get born tall, but grow to be tall. However they never choose to or worked towards being tall.

If you ever heard something like “XYZ is turning the kids gay!”, its a lie. Differently to being tall, sexuality is something internal, something you feel. And many people are being told that what they feel is wrong. So they believe it is wrong and surpress what they feel. This leads to misserabke lives, depression and often violent/abusive relationships because they are internaky unhappy. If you tell them it is okay to feel what they feel, they are more likely to accept who they are.

So telling people that it is okay to be lgbtq+ leads to more people being openly lgbtq+. They always were. They didn’t “turn gay”. They just didn’t lie to themselves and surpress it.

Why are you the way that you are?

(And why is your account all tech and now… this?)

You could also ask why we have sexuality at all, and since we do, why isn’t it evenly spread across the spectrum?
Obviously there are mechanisms that guide our sexuality and gender identification, and they are not 100% the same for all men or all women.
It’s simply a natural mechanism with some variance that occur in most things.
Why are some people introvert?, Why are some people tall? Why are some people strong and others fast?

It’s like when you ask how magnets work, and it turns out they kind of work like everything else.
