Lots of these faggots are simply very very submissive men. Very few women want anything to do with a deeply submissive man. Even fewer want anything to do with a deeply submissive and physically unattractive man. So, to solve both, they adopt some aspects of femininity. It's a lighter version of a subsection of trannies. Then, they go after men, to finally get the domination and approval they crave. Degenerate faggots love submissive unattractive men.
So they fag out to get their sexual needs fulfilled. Lots of them don't even like dudes in the classic sense a normal (lol) gay man does, they're just one of the few groups who satisfy their urges. This is why you'll see sissy faggots also doting on extremely dominant man-hating women, another group that will give them what they crave
