If you thought you were a true ally, maybe it’s time for some introspection.
I would agree a straight dude who feels the bizarre need to LOUDLY DECLARE his lack of attraction to trans women is probably just expressing transphobia.
If it just genuinely the case a straight dude has never felt attraction to a trans woman and doubts they ever would, I mean whatever you can’t control who you’re attracted to. I’d say just yah know, keep that to yourself and if a trans woman ever does express attraction to you just politely say “thanks but no thanks”.
