Oh my… conflation galore.
"Sissy" is not a gender idenity, it is a kink, usually including crossdressing & a sexual attraction to men. It is the old slur for effeminate men (regardless of their sexuality) and has been re-appropriated for the kink. Yes, the sissy kink hypno files often include some very unsavory stuff, usually in those intended to humiliate (and thus desensitize) the listener, some of it is homophobic, transphobic, misogynist, racist etc. The humiliation is not core to the kink, but a lot of the creators use it.
The G&B community has always included some men who are gender non conforming. They are no less valid than any one else who is gay or bi and macho. For hetros it was incorrectly the campy stereotype well into the 1980s because gay fem men were visible & often more out of the closet than many others (Dr. Frankenfurter in the RHPS, Albin in La Cage aux Folles, etc.. are examples for what hetros pictured). Some gay men may not find fem men attractive, that's fine, that does not make being fem or into various fem kinks "homophobic". Not everyone is the same (very fortunately), attraction & self image & presentation differ. Part of being human.
Transgender says nothing about one's sexual preference or what phobias if any one has and is no more a "mental illness" than is being heterosexual or homosexual or bi.
Both gender identity and sexual preferences are probably rooted in one's neurobiological development and innate (so not "hypnotizeable", best case they can help one recognize a bit more about them self) and the reason why groups like the ADF & Co. are so vehement in attacking the very small transgender community. They believe if they can have transgender reverted back to a "mental illness" status they will then be able to do the same for same-sex, do away with decades of same-sex equality legislation and even reintroduce their cherished old discrimination & sodomy laws.
If those who are posting here and elsewhere on the /hypno board really are gay, perhaps reflect a bit on who your friends are, who's crusade you are fighting for & in the end what the consequences they intend for _you_ are.
I do find the complaints a bit amusing on the /hypno board here, where 90% of the content is sissy kink & feminization centric. I always wonder what draws such posters to read this board, shrugs.
