Ana, I don't think people have lost interest, but as i return from time to time (when the other life allows), I get the impression that the thread is going round in circles.
Whilst opinions are strongly held and often supported by facts, it becomes clear to the occasional posters, if not the very active ones, that civilised accord ( I don't use "agreement" as a concept) will never be reached. We interpret events, both past and current, by our political persuasion, although occasionally, we see the slant the other shows us. However, debate can become tedious if there is no time limit!
Regarding populism vs democracy, many papers have been recently written examining this( available online) and they all, in their conclusions, return to the idea that populism in itself does no harm to democracy if representation is full and if there is no erosion of democratic principles by prejudice, intolerance and self-righteousness. Of course, democracy dies if the leader's powers reach the level of demoguery and, ultimately, dictatorship. The leader's power was mentioned quite early on in the discussion.
Demoguery was at the beginning of this discussion, and it returns at the end.
