I don't believe I am anti-trans.
I am a cis woman (don't jump on me for using that word, I think it is useful in this context). I know three trans women, one many years post-op, one very recently post-op and one probably pre-op although I don't know her as well.
The first two are lovely. I know quite a lot about the second one's struggle towards accepting that she was trans, overcoming some lifestyle-related obstacles to starting treatment and now having had treatment and being so much happier. I have no doubt whatsoever that she had genuine reasons for transitioning and has no intention of hurting or defrauding anyone, and that being a woman is what is healthiest for her. The first one, I knew as a woman for a long time before I even knew she was trans. She is oldish and leads a perfectly ordinary life. I have actually been in the dreaded toilets with her (before I knew she was trans) and she certainly didn't try to make a move on me.
The third one is quite an annoying person, but not for reasons specifically to do with being trans. The nearest I ever come to being anti-trans is wishing I didn't feel that I can't be as snappy with this person as I would with a cis person who was equally annoying, because it might be perceived as prejudice.
I will continue not to be anti-trans unless something happens to convince me that the majority of trans people are out to do cis people harm just because they are trans, and that doesn't seem at all likely to me at the moment.
