Do y’all still have faith in it as an idea/ideal?

Of course. That is if we're making the distinction between democracy the ideal and liberal democracy the political system.

the us is a plutocracy

democracy as a concept must be tied to economics rather than politics imo

idgaf abt political mechanisms as long as they represent economy and labor in a democratic manner

Yes I do.

Americans are just too stupid to vote third party, and think Democrats and Republicans are the only options.

Of course. But democracy can't truly exist under a capitalist system.
