Well said!
Ultimately, I see both AGP and HSTS labels as being rooted in overt homophobia and transphobia.
If a trans woman loves women, they think she must be obsessed with herself.
If a trans woman loves men, they think she must be a failed gay man who is trying to become heterosexual.
Somehow, gay trans men get ignored here, and straight trans men are just seen as confused lesbians. I notice, as well, that bisexuality is often erased entirely in these discussions.
It's founded in such ridiculous logic, and it's never applied to anybody but trans people. Nobody thinks that cisgender gay men and lesbians are sexually attracted to themselves as a default, and nobody thinks that cisgender straight people are exhibiting some kind of fetishistic interest in those of different gender than themselves.
The logic is just silly and falls apart with any amount of scrutiny.
I guess my personal response to such a stance, aside from blocking the offending party as you often do, would be why should it matter? As a sex-positive person, I can't bring myself to care about what makes someone attracted to another, as long as the attraction is healthy and leads to consensual relationships, should one be interested in pursuing their attraction at all.
It all seems to come down to genitalia, and I can't bring myself to validate concerns that are so grossly and obsessively focused in what's in my or my partner's pants. It's really nobody else's business.
