To the OP, YABU. You're setting the bar of 'anti-trans' in the wrong place, and including the vast number of reasonable people who are fine with trans-identifying people but want to resolve the conflict of rights caused by the demands that some of the lobby groups have made.
Like many other posters, I'm not anti-trans: if someone believes they're of the opposite sex or no sex at all, and that belief is important to them, fine, go ahead and hold it. No-one should be harassed for that belief, nor discriminated against for living their life as best they can in the light of that belief. I don't say that to trivialise the belief. I have friends for whom religious beliefs, e.g. that they have a soul saved by Jesus, is core to their sense of who they are and their purpose in life. I fully support their right to hold that belief and live according to it, up to the point at which they try to make me profess the belief or practice it, or it has other impacts on my life, or infringes the rights of others. E.g. if they were to ask me to affirm that they do, indeed, have a soul saved by Jesus, we'd have a problem. If my workplace were to ask me to state in my email signature which church I go to, if we started workplace meetings with a prayer and a hymn and anyone not singing the hymn was ostracised by colleagues, I would object (hopefully out loud, but depending on the situation I might feel coerced into participating). That wouldn't make me anti-Christian.
In the same way I have no problems with trans-identifying people believing they're of the opposite sex or no sex at all, up until the point at which it impacts on me and/or infringes the rights of others. I'm anti the absolutist way in which, in the name of trans rights, it's become impossible in some places to talk about women's rights, and to defend the protections and provisions that (some) women still need, deserve and have won at cost. If you say that anyone seeking to discuss how to retain those rights is anti-trans, then you're not just being unreasonable, but you're part of the problem, and part of the reason that the conversation has become so 'toxic'.
