As a straight guy, I’ve gone out with biological women who identified as non-binary. I’m not attracted to their “gender”, I respond romantically to the female sex

This right here. TRAs try to validate genders so much, yet they have no clear answer about non-binary people. Guess what, if an attractive woman identifies as non-binary, a straight guy will still find her attractive.

About Reddit... I think it's fine if people wanna stop using Reddit altogether, for any reason. But for those that wanna keep using the platform, I think that pro-LGB subs should keep existing, we should keep resisting.

We shouldn't be pushed out of all mainstream social platforms just for being homosexual. And sure, platforms can have their own rules. But they should be clear about those rules. What we see is double standards. LGB subs get banned for any small excuse while anti-LGB subs keep attacking us. And this isn't even just TRAs, there are plenty of subs for religion on Reddit where it's fine to spread homophobic ideas. There is nothing in Reddit's rules that forbids defending homosexuality, or forbids LGB-only subs.
