The biggest eye opener after GamerGate started and the left decided they needed to do a purge in the culture war of all non-Marxist elements was just how all this shit was just barely under the surface, and took absolutely nothing to drag it out. There was just a thin veneer of respectability covering over some of the most hateful, ignorant, bitchy, passive aggressive, snotty, entitled, arrogant fucks you could ever imagine, and a little friction (Gamers telling them "no, fuck you, you're wrong") was all it took to expose it.
And then Trump won despite everyone they deemed fit to be allowed to speak in their presence telling them exactly what they wanted to hear for a year or more, and the veneer didn't just flake away in places like during GG, it openly fucking shattered.
What's amusing is the left, especially the radical left, still "identifies as" the sane, rational, respectable party, the only one worth speaking to or about, whom everyone agrees with, who is the party of anti-racism so can never have a bad opinion on race, yadda yadda yadda. They honestly think they're the party of the working class.
The delusion is real.
