Direct democracy is very prominent on a local level in at least Cuba and China (at least that's my impression), and probably in the DPRK, Vietnam and Laos, too. Having no elected representatives is completely unfeasible on a national level for any country with more than a hundred thousand or so citizens (and even that's stretching it IMO -- I doubt most people would be interested in keeping track of the effects of policies and events on tens of thousands of other people, especially if that's not their full-time job), which is why AES countries use representative systems but ensure that officials can be stripped of their positions if their work is unsatisfactory. With that said, a disagreement on that front doesn't justify insults
(obviously, people who reject you for recommending Capital are just unserious and/or ignorant, likely both)
