Women treat men who don't want to have sex with them as orbiters too. They only want to take from this "friendship" but don't really give anything back. A female "friend" will just put you through a bunch of shit tests and make everyone know that you're just her friend so that you will end up looking like a beta orbiter anyway.
If you have a female friend as a single man, you will look like a beta orbiter in the eyes of the people so ask yourself if it's worth it. All it takes is one photo together and her pointing out that you're just a friend and you'll end up like those guys in friendzone memes, looking like some weak cuck.
It's just the way society is these days, although I don't remember any point in history where friendships between men and women would exists.
