Anyone on here ever watched Dr Edward Dutton? He has a channel on YouTube called "The Jolly Heretic" he talks about how lack of Darwinian selection causes an increase in negative mutational load in the population. The brain is 80% of the genome so physical manifestations of dysgenic traits are likely to be accompanied by mental impairment.
So yeah - these degenerates. Liberal women, soyboys, SJW's Vegans, Antifa are all the expression of the dysgenic effects of modern industrial society.
The left at the moment consume a much more homogenous selection of media than the right do. If you look at political YouTube leftwing views are dominated by a handful of large media establishments or "permitted brands" so CNN, MSNBC, Buzzfeed, Huffpo, TYT. If you watch mainstream media it is just blatant propaganda which just repeats the same identical message verbatim across numerous outlets. You see this with the endless "Trump = Hitler" or Corona hysteria. So you have a series of very simple narratives repeated ad-nauseum which form their world view.
Now add in social media which has algorithms which feed certain content to people based on what engages them and feed them a never ending diet of this none stop. The left tend to be higher on neuroticism. Basically you have mentally impaired media conditioned neurotic people being driven insane by social media.
Then add on top of that the obsession since the 1980's with "upward mobility" which meant everyone had to go to university and get a degree - never mind the more people have a thing the more its value deceases. So you funnel all these people who aren't very bright - midwits and halfwits into liberal arts courses and feed them a diet of critical theory, identity based politics and social justice. Now these people have a stunning case of the Dunning-Krueger effect on top of their simple minded media narratives and social media induced insanity.
So shit in shit out really.
