I can’t talk to what the female experience is with being gay or trans because I am male, but I can cite some observations I’ve made over the years as an American gay male.
I think guy-on-guy homophobia can get very bad. Murderously so in some instances. Where straight and questioning males seem to be able to enjoy the reality of lesbian intimacy, these same guys can find gay intimacy abhorrent. I think it is a fear of emasculation, especially among questioning males. This fear appears to be visceral and instinctive for some guys. Their insecurity with their own sexuality is such that any challenge to it needs to be confronted with overwhelming force on pain of perceived social emasculation before females and male peers. This can make things dangerous for gay males who’s very existence seems to challenge these insecure males. This is particularly true when the males are young and just finding themselves socially and sexually.
American society has either inadvertently (or by design in some quarters) given license to males to ‘defend their sexual honor’ by any means necessary. This license has opened the door to bullying and outright violent crime being visited on gay males by some straight or questioning males. As homosexuality becomes more normalized across the nation, this license is slowly being revoked, but it is still in effect in less progressive parts of the country and among older generations.
Because of this, I think that gay males in America do still face significant challenges to their physical and social safety in society. It is far less than what it was when I was a boy a long time ago, but it is still a significant challenge.
