Don't you get it? /g/entoomen like OP have been jacking off to anime lolis all their life. Now a trans person comes along and uses the pictures of those anime lolis as their avatar everywhere.
No wonder /g/entoomen are pissed. They just realized what the perfect little waifu they always dreamed of translates to in real life.
It makes them mad when trans people associate themselves with their precious anime waifus. That is the only real reason.
