I’m sorry, your post is too long for my brain to handle. Obviously some people are transphobic. But i don’t think losing attraction for someone after finding out they used to be a different gender necessarily means someone is a bigot or is transphobic. Sexual and emotional attraction are very complicated things. I can’t say for sure but I think if I were a lesbian and not remotely attracted to men I might not be attracted to someone who once had a penis.
Some people are transphobic and transphobic people are not attracted to trans people. It does not follow that not being attracted to trans people means you’re transphobic though.
