"Filthy normies" and such is always a hilarious bit of nerdspeak. But the crux of it, to some degree, I am normie and normie am I - i.e. it's human nature and in all of us. Facebook or reddit never set out to say "Hey, I want to be evil and polarize society". They simply wrote an algorithm, told the algorithm, "Hey algorithm, find out what people like to read, and give 'em more of it". And people answered "we love drama, we love juicy, we love gossip, we love the grey area" which it turns out, gets people worked up, polarized, and keeps eyes on the prize. Just as the original internet was a scholarly interaction method and turned out to be a porn delivery mechanism, so too with social media being intended to join people together and yet it splits us apart. Are we to blame the one who held up the mirror only for humanity to see its own ugly visage and become angered by it, hard to say. Probably we should blame them if they made 9999 gorillon dollars from it, which they did and are doing.
