In short: Liberalism (in the sense of limitless social freedom without responsibility and real consequences for shitty actions for women due to abortion/uncountable security networks/male simpdom/etc.), this was always ingrained in human nature, but the deconstruction of restrictive social orders has allowed humans to follow their instincts (freedom to follow whatever you want is nothing good - as we see nowadays because most men will never have what it takes to get any woman due to their fetish for height/looks/etc. regardless of their own quality, it was always their nature, but now they aren't shamed for it but embrace it/have the freedom to follow it, prior to this you had the worst impulses of humans under control with social shaming and the law) - in the absense of the law we become animals again, this is the black pill about society/human nature and the justification for the existence of restrictive social orders
