"Sexuality" is a desire.

Only if you change meaning of word "desire" to mean something else. In modern day of post-modernism everyone is just changing old words to mean something they want them to mean.

Also, does this mean that homosexuality just don't exist and it is just a preference, a kink?

They do not have the mental capacity to desire something, let alone have a goal. They do anything that's in their way.

They do have mental capacity to undestand a lot of things, they even have morality. Humans are not that special, don't be religious.

Other species do not have "sexualities".

And yet we see homosexual primates, birds, cats and other animals, who are refusing to mate with opposite sex even if they "are on heat" and only want to mate with same sex. Female bonobo even have tribadism among their lesbians, who only want to have sex with other females. If sexuality did not exist, we would not be observing such behaviour in animals and animals would not care with whom they have sex, and yet they do.

The entire point of "born this way" was so homophobes pity openly gay people.

No. It never was. It is just stating the fact. I was born gay, so deal with it.

Does saying "I was born black" is to get open pity from white people? You are making no sense.

That's not the same as sex and height that can not change and one can not choose.

It is same, as we can't chose it. Your own bisexual experience is just your own and it is different to experience of homosexual people. Yet you are calling that "you have chosen to be homosexual" and then "bi"explaining homosexuality to homosexual people and saying that our whole life of experience is just wrong and we actually never had it, but you know better. Just same way as transwomen mansplaining to women what it is to be a woman and how they have chosen to be one.

And you want "sexuality" to be innate so people who have a different view on "sexuality" be labelled as "bigots", as though they are on the same level of "racists".

If my opponents hate something or want something, it does not mean that I love that something and want opposite to what they want.

I am just saying how it is. Why can't I say who I am? I was born gay and it is okay. Does woman caon only be saying that she was born woman only to oppose wokes who are saying that you are chosing to be woman and not being born as one? Obviously no. Same with saying about homosexuality.

Other question is why you so desperately want to be included in group you are not part of and group experience of whom you do not understand? And why do you want to "explain" them how their experience is wrong? If all of them have different experience to yours, maybe you shouldn't apply it to everybody, like your own experience is universal? Don't be so narcissistic.

Also, how exactly society is pushing to be gay? Especially somewhere like in Iran or Taliban, where you will be tortured and then killed for it, for example? Are homosexual people there just liking extreme pain and don't value their own lives?
