Democrats care about messaging (especially to centrists and republicans). Leftists care about actions. Leftists tend to hate imperialist action with a progressive hashtag more vocally because it’s just as deadly and twice as deceitful.

Assuming the metaphor is that western society is a mouth of teeth, it was full of rot before we were born. Republicans want to eat more candy. Democrats want to eat the same amount of candy republicans ate 4 years ago but brush every couple years at the voting booth in the hopes that the rot gets brushed away. Leftists want the rotten teeth pulled since it’s starting to affect the entire system now and will soon destroy the world cause heart disease if action isn’t taken.
