Why is it considered gay for guys to wear womens clothing but girls can wear pants ect?

This shows how deeply the idea that "women are inferior" is buried in society. It makes "perfect sense" for a woman to aspire to manhood, but why would a man "descend" to the status of a woman?

It is also possible that men, conditioned to respond to threats, see a man in woman's clothing as dangerous, but don't feel that way about women, no matter what they're wearing. (This is a fairly recent development. As recently as the middle of the 20th century, the idea of women wearing pants was widely seen as "threatening".)

Well as A second Opinion, I agree with the above, but I think Guys are considered gay for crossdressing because they are seen as feminine just like real homosexuals which most men don't like. But the fact is 90% of crossdressing males are heterosexual. Most gays don't want to be women. Well it is confusing because a large portion of gays do put on make up and go into fashion. But they don't crossdress i.e. wear women's clothes.
