> a democratically-elected official can wield the power of the state against you and harm your interests just as much as a dictator can

Really? Can they? Because in a functioning democracy you generally have recourse to courts, tertiary adjudication of various forms, a (relatively) free press that you can try and interest in taking up your story, etc. In a brutal dictatorship you're likely to have none of those, and to go missing in the night if you try and suggest that you should.

It's absolutely right to oppose politicians you disagree with - that's what political engagement is all about! But beyond a certain level, hyperbole (and the general sense of "they're all the same") simply does serve to undermine not just democracy, but any rationale for political engagement vs. simple rioting.
