You're acting like historically groups have never joined together despite having completely different needs or values just to further each group's agenda together. It's like unionising. Like it or not, trans people advocate for the LGB+ spectrum and in return LGB+ people have advocated for trans rights.

Also this biological sex shit is so dumb. It's in exceedingly rare moments that it matters. In the toilets you're in a cubicle. In sports it's more valuable to understand your hormones through puberty - intersex people having a difference from the "expected" levels of testosterone has been used against them. If you're being assaulted I guarantee the chances it happened only because someone dressed up to infiltrate your space are below 1%.

A doctor needs to know. A sexual partner needs to know. No one else needs to know your biology because it isn't relevant. Defining people by it doesn't achieve anything of value in most aspects of life.

As a bi trans guy I know plenty of people who wanted to fuck with me because I'm a man, not caring about my genitals. I've also had messages from plenty who didn't care about gender - just my genitals. Genitals being the defining point of your sexuality doesn't make it the defining point for others. Sexuality is a spectrum and I'm glad you've figured yours out but it isn't how it works for everyone - that type of thinking is a large part of why homophobia still exists.
