I think a multitude of hot takes fit, but I really dislike when liberals go after socialists for completely unrelated perceived flaws. Y'know, "Che was a homophobe", "~~literally every 19th century European~~ Stalin was anti-semitic", "Gaddafi was misogynistic". Even if those accusations were completely true and not based on astroturfed rumours or ridiculously over-blown or taken out of context, what does that have to do with their views on capitalism? If it turned out that Karl Marx really fucking hated the Irish for no reason, would that make all his writing useless all of a sudden?

Cheating a bit, but I also had an acquaintance describe their near "Westminster MP" level salary for a remote job as "barely making it into the middle class", and that has been haunting me for months.
