I don't understand arguments like "Some people are uncomfortable with men in dresses so there should be no men in dresses"
I'm sure some people are uncomfortable with people in pants. Should we ban pants?
Maybe some people are uncomfortable with the colour red? Time to ban all red in FFXIV?

This is a Japanese game... One of Japan's biggest entertainment industries is "visual kei" where guys are crossdressed as Renaissance princesses. There are like 100+ gender-bending animes and mangas, many of which are/were insanely popular in japan (e.g. Ranma).

So the argument that something should be kept out of a game because a few people find it uncomfortable and weird just comes off as kind of ridiculous.
It won't affect gameplay, it's not going to scar a bunch of people for life, etc.

Saying it's unlikely is fine
Arguing that you don't think people should have MORE CHOICE in a game is just a veiled way of saying you aren't comfortable with it
