Gender "identity" is not sexual orientation. Homosexual and bisexual people are mostly accepted in my experience. Gender dysphoric troons who identify as women (NOT transwomen) and pass as female had reasonable acceptance before the gender ideology people came along and hijacked the movement. These newcomers, representing 99% of all people who fly the tranny flag, almost all of which suffer no gender dysphoria whatsoever, are the cause of almost all transhate. Though many of these people are terrible and ugly, the people themselves aren't the reason I hate them. It's the dangerous ideology, the delusional thinking, the cult nature of the movement, and the targeting of vulnerable people, including children. There is no valid argument to be made in defense of these freaks.
The 99% of the troon cult decided that gender dysphoria was not a required element for trooning out. They say if you "identify" as a thing, you are that thing and you always were that thing and if anyone says otherwise, they're wrong and you're a victim. Most of them have autogynephilia, a number of them are pedophiles and narcissism has a very high representation among them. None of these freaks, nor their recruitment victims, are having their lives improved by trooning out. You can't fap to the thought of being female if you no longer have a cock. The social impact of inevitably cutting off all of your friends because they're not towing the tranny line is arguably almost as bad as the physical ramifications of trooning out, especially if you don't pass and let's be real, a majority of these people don't even come close to passing.
The other 1% are welcome to troon out as a treatment for legit gender dysphoria, and I think most reasonable people are okay with this regardless of how they feel about the other 99%. But if they're unlikely to pass, it might not be the best medical treatment for them. Schizophrenia drugs have been shown to treat gender dysphoria while remaining your birth gender in at least some people, but it seems this line of research is vastly overshadowed by the much more lucrative trooning out in the medical community.
The alienation experienced by troons is completely different than the alienation experienced by gay men. You seem uneducated on what it's actually like to be gay, or trans for that matter.
