You could say that when they inevitably end up disappointed by reality they will be hurt more, but people can live in delusion for years and be happy with it, then after a setback or disappoint they can go back to deluding themselves and become happy again.

For instance, who do you think is happier? The incel who refuses to betabuxx because he knows that any wife he could get would prefer Chad? Or the bluepilled cuck happily raising “his” children? Who do you think is happier? The 40 year old spinster who never got married because “all men are trash”? Or the 40 year old bluepiller who believes her husband “loves her for her,” all while he’s fantasizing about some 16 year old instagram model any time they fuck? The bluepillers, of course!

Reality is overrated. It can be useful to be aware of it, but it can also be limiting. To the people on this subreddit, it’s worth keeping that in mind. If you can delude yourself, you should.
