PC? Politically correct? I don't think we really need to go down that road.

I think a lot of these changes come from people trying to make fictional, impossible characters relate to real human beings and human labels.
Are you sure it's not the opposite? Couldn't it be that people are trying to take a term that originated in anime circles and adapt it to real life? This term was in use in anime circles when I was a child, so it's at least 30 years old. Quote: "It's a trap because it looks just like a girl". I didn't even know it was used in other social circles until you brought it up and I was exposed to a lot of slang when I was young. And I can't find any similar definition for the word on Wikipedia or any dictionary. I would assume any mainstream use it's getting is only recent.

Anyway, this is apparently the reason Danbooru changed the tag to otoko_no_ko. By doing so, they avoid disputes like this regarding it's meaning.
