Kayla's suggestion about prostitution was positively revolting. That position seems to hate just about everyone: incels should just go solve their problem illegally in a way that happens to be the antithesis of feminism.
Sex work is in no way, shape or form the "antithesis of feminism". And I think it was clear that Kayla was suggesting that such work not be illegal, not that men go solve their problem in an illegal manner.
Though in practice women can end up pimped/trafficked. Or abused by their clients, with no legal recourse... which is of course why pimps exist, because having somebody to maybe-protect you may be preferable to no protection whatsoever.
Of course, legalizing prostitution cures a lot of these ills.
