this history perpetually repeating itself is the context that liberals and conservatives alike seem to lack when analyzing politics and there's no clearer sign of the american version of this than the likes of biden being heralded as the most pro-gay president ever when he literally ran on an anti-gay platform during his first presidential attempts and espoused anti-gay marriage talking points until it was politically convenient; then signed the most anti-trans bill in history and also hobbled the equal rights amendment at the end of his term.
american liberals, especially, already know that democrats are leopards that can't change their spots, but still somehow believe that those same leopards are not going to eat their faces after every election. they've now starting damning their fellow liberals for not voting and i it's not going help anything, like it didn't help the weimar republic; thus repeating history.
