I think this is true across the entire political spectrum in the US. Our social media reads as a mix of apathy, nihilism, signaling and historical ignorance. In other words, many of the people who by all rights should be happy with their comfortable lives in the wealthiest country on earth have somehow decided the world is a terrible place, everything is terrible, it's all going to hell, so let's just pull whatever thread seems likely to piss someone off who's got it slightly better than me and see what unravels. Americans are ingrates.
