I'm not an incel in case you try to dismiss what I say by calling me that but these guys, as far as I can tell, object to the fact that women claim, repeatedly to the point of absurdity, that looks don't matter, height doesn't matter and they're only attracted to "deep" traits like intelligence and humor. Yet they then go around showing off about their boyfriend's physical traits. (They also object to men judging women based on their weight and height, one of which is a choice and if a guy showed off about how tiny and skinny his girlfriend is I doubt you'd have any trouble realizing what's wrong with showing off.)

The truth is that looks obviously matter but if you bring it up in a group of people they act like you're talking complete nonsense and if you bring it up online they act the same way. In fact, on an old account I wrote on some relationship sub (about what men and women find attractive) what, in my experience, I thought women were attracted to and almost got banned. The funny thing was that 2 of those women that berated me ended up pm-ing me and ended up sexting with me after I sent pics. They both said "I thought you were gonna be some fat ugly guy" and then the next message from one was "going to bed now... naked".

When you experience stuff like that AFTER a woman says she is attracted to looks and intelligence then it makes you realize how much bullshit society pedals. So in that context it becomes annoying to incels. They've been misled about what women find attractive. They were given false hope. It's some evil shit when you really think about it.
