Why does most anti-trans rhetoric seem to focus primarily on trans women?

This could full-well be due to gaps in the media I consume, but why does it seem like most of the common talking points (e.g., bathrooms, sports, etc.) focus primarily on trans women? Even when expanding and considering things like the transphobic jokes some comedians make, the material still seems to be highly-focused on trans women. Is there a particular reason why trans men don’t seem to be as targeted?

I really hope this doesn’t come across as pot-stirring/upsetting or anything. I’m genuinely curious to understand if this is a real thing or if I’m just misinformed, and I figured this was the best community to ask.
