I’m not kidding. Urban areas with a high density of population are always more left-wing than rural areas. Lonely losers are the ones who become incels/groypers and shit. Workers who worked in small businesses with few colleagues were the most likely to support the literal NSDAP in the 30’s. The more people you talk to the more likely you are you support left-wing ideas. I just have to make a shit ton of friends and the revolutionary spirit will bring about communism.
