I don't think that the legalization of same-sex marriage is responsible for this trans-scourge; it's only a symbol, and what it symbolizes isn't anything negative. The blame lies elsewhere.

Same-sex marriage represents the de-stigmatization of gay and bisexual people: our being acknowledged as normal members of society. Not that it's the only form this takes, but it's the most convenient shorthand for it.

Did LGB normalization open the door to imposters like "transbians" and "gay transmen"? Yes, in that it made calling oneself gay much less risky. But this had to happen; it's what LGB rights are all about. The problem was allowing people in who didn't belong, because gender-based identity is not only nothing like our own bio-sex based identities, it's actually antithetical to them.

Same-sex marriage didn't cause that. Just look at the sad example of what was done to Michfest (the Michigan Womyn's Music Festival): "transwomen"'s sustained assault on it began in 1995, twenty years before the Obergefell decision. So the T didn't need "gay marriage" to start violating other's boundaries; that was already well underway.

So what did cause it? Confusion, I think, between being same-sex-attracted and being a libertine– which is to say, a sexual hedonist without any brakes, moral or otherwise. Of course this is the perennial accusation hurled at LGB people, and a perception that we continue to struggle against... but ironically there are those who embrace it. And not all of them are straight “trans” people motivated by sexual fetishism. It’s sometimes us. For different reasons, though, I suspect– namely the legacy of the closet. If you’ve grown up being forced to hide your sexuality out of shame and fear, and then gotten to the point where you can finally act on it... any restrictions could feel like a threat; as though the closet is back. And you may reflexively resist. Thus leaving you vulnerable to exploitation by the real libertines, whose agenda you mistake for your own.

But in any case, OP, your opinion to the contrary certainly doesn’t constitute hate, and shouldn’t have gotten you banned. Especially when organized attacks on the right to same-sex attraction by the T and their flying monkeys never receive the same treatment.
