Those "Marxist" leftist perfectionists do not acknowledge the huge gap between deep blue & deep red states in life expectancy, minimum wage, reproductive rights, education, infrastructure and numerous other measures. They are racist a$$holes just like their GOP relatives, friends & neighbors.
I don't totally agree but I can respect that I don't have the same lived experiences/lived truths that other folks have. I'm also not referring to Bernie Bros here FWIW, but more thinking back to campus activism days.
These ARE the Bernie Bros 2.0. They are a key part of the GOP. They're nothing like the campus activists of my college/grad school days at all. They work for the Republican Party.
