Artichokeleaves, and Kittenkipper,
I think we disagree less than you think we do! Mind hearing me out a bit?
The question I'm trying to answer is why is the T, a gender orientation category, represented in the LGBT acronym, which at face value seems to also exclusively be made of sexualities.
What I think brings them together is gender non-conformity.
I think what's getting confusing in the above paragraph is the the idea of gender non conformity. When you say that you probably hear non conformity in gender presentation!
What I am saying is, is that, even without any changed gender presentation (a lesbian acting and dressing exactly like other women around her), the simple fact that the person is homosexual (so a woman who likes women) is, in itself, a gender non conforming characteristic. You can be femme, but just you being gay does not conform to prescribed patriarchal gender roles.
Because, by being gay, you're not going to have a romantic relationship with a man, which is a large part of the gender expectation for women.
And I think yours (and my) experiences of sexual harassment at the hands of men come from, rather than simple sexual desire, a place of gender policing and want of control. Just like other forms of sexual violence, it's not about sex, it's about power, and men want to exert their power over lesbians, and trans women, so make both fall in line.
Take your example of those terrible men who made fun of you with the V signs and tried told you to try their dicks. They singled you out with this particular harassment. While some of them probably just wanted sex (so many always do), the majority probably did it to point out and humiliate you for your difference. For your love of women. For you not wanting to be with men. You weren't conforming to the role you were prescribed. By liking women you came out form under their influence, so they harassed you and made you feel lesser and made you feel unsafe in order to shame and bring you back into their control.
Though you might not believe it a lot of similar things happened to me!
I live as a trans woman now but in high school I was a somewhat feminine bisexual boy. Though I was much more often in relationships with women (usually other bisexuals), everyone who didn't know me saw, basically, as a gay guy. I didn't dress partiuclarly femininely, but I put effort into my appearance, and naturally acted in a traditionally feminine way. Throughout I had gender identity issues, didn't like hanging around other men, and mostly had friend groups and friendship relationships with women. I wouldn't jockey on the male hierarchical ladder. I wanted no part of it.
Funny thing was, I never got made fun of for me being attracted to or having romantic relationships with men! It was always the me being feminine part. But, despite the lack of focus on my sexuality, the main way in which I was bullied and policed was through sexual harassment, usually by straight men.
And these men were certainly straight. Not a gay bone in their body. Had relationships with women. Sexually harassed other women. Just weren't gay. Buttttt they would constantly sexually harass me. Whisper about sex in my ear. Grope me. I was once cornered in the locker room. Not because they were particularly attracted to me. But, because I wouldn't play the dude game. I was different, not in their control, and therefore power was exerted over me through sexual harassment.
So, in both cases I understand the root cause of this sexual control exerted by men to not be sexuality per say, but our respective traits of gender role non conformity. For you, being attracted to women as a woman, and for me being feminine as someone who was assigned male at birth.
