Many libertarians like to say that there's no difference between the two parties, & while the Republicrats are often quite horrible too, the Democrats are just far worse.

Democrats have always been the party of slavery & eugenics. They traded their white hoods for Planned Parenthood & Pharma badges, but they are still promoting the same policies. They want to take more of what people earn, they want a govt monopoly on weapons, they want to control & censor what people say, they want to control what you eat, they want to control over travel, they want to control your access to money... Every potential problem (even the one's they create) is just another justification for more power & control.
