I used to constantly hear incels on /r/TheRedPill bitch about women "standing them up" on dates. Saying that they "do it for fun"

I don't get it. Why would someone "do it for fun".

My theorey is that lets be real incels are creepy deranged fucks. so I wonder if some women out of fear say: "yes" to the date fearing that if they say: "no" the incel they are interacting with will go ballistic. But then the woman cut them off to get away from them.

is my theorey true?

Plus can most women tell if a man is an incel by looking at him/his mannerisms etc?

Thanks for explaining this to me.
