I think men can help by stepping up and calling out this behavior for what it is

As someone who used to be an incel (albeit in isolation), one sympathizes. If there had been forums for people like us back then, I would've definitely partaken. First, society constantly shoves tits and ass in men's faces (usually for the purposes of selling them stuff), tells them 'this is the thing you're supposed to want', ridicules them if they can't obtain it, and then makes it illegal for them to pay for it.

If they dare join a group that wants to teach them how to be better with women, they're accused of objectifying women, and are told 'just be yourself'. Well, shit... if that worked, they probably wouldn't have been alone for the last decade, playing with Mr. Winky.

And people wonder why they're pissed off ...
