The director said specifically that LeFou is gay and has feeling towards Gaston that vascilate between "wanting to be him" and "wanting to be with him" and would have a big moment.

I have nothing against gay villains as long as they aren't a trope. Hell, the book I just finished had a gay villain but was a typical evil villain that happened to be gay (wanted to tap the protagonist who was incidentally gay as well). However, if this is Disney's first "official" gay moment then it is weird to pick LeFou given their history of gay-coding villains. I am in no way saying it will be bad, hey it might work and be good, but I see potential for it just being the same old trout.
