As an American, I would also say the most loud and relentless proclaimers about our democracy are also our right wing voters. Nationalism is a hell of a drug. I wouldn’t necessarily say it’s only our politicians. I went to school with people who unironically would start USA chants.

Though I’m not saying we don’t have the same thing on the left. I think more of America’s left recognizes how shitty our county actually is for regular people.

I know I rambled a bit there… Anyway, I agree with your point entirely about the loudest they rant about democracy, the less there actually is.
