PCM

An utter shithole filled to the brim with right-winger shit-flinging barbarian monkeys who think of themselves (the "auth-right") as the kings of the Internet castle and the "lib-left" as the dirty rascals. They often use crying and masked Wojak shittysketches to make them feel like they've justified their opinions about themselves. Like any other pathetic snob-nosed alt right, tbey also think liberalism = socialism = communism.

Average PCM user: Har har, i saw a lib-left produce a legitimate argument against the auth-right, time to portray them as the triggered Wojak to fully own them!
