Are we sure this isn't someone giving actual healthy advice and couching it in a way that incels will accept, thus possibly leading them out of the incel lifestyle?
I mean, think about it. If you can convince an incel to start asking girls out, especially if you disguise it as a way to "lower their self-esteem", then they'll fear rejection less and do it more often. Eventually, they'll probably find someone who's willing to give them a shot (assuming they're not publicly displaying their incel status), and the positive interactions with a girl could lead them out of inceldom. It's... a pretty smart move, IMO.
