The weird thing about this is that you're relying on a clear sense of your own identity (that you are not gay, because if you were you wouldn't challenge someone to prove you wrong, you'd just say it) to deny the value of other people doing the same thing, but with a different answer.
To wit: you're yelling about your own sexuality in an argument about how we shouldn't have to hear about someone else's. You know how all those woke folk talk about "privilege"? That's what privilege is. Trans kids don't get to say stuff like that on the internet, only straight guys.
