While I don’t agree, I do believe it’s a common perspective and one that’s important to have dialogue on.
While for sure an imperfect response, I would say that no democracy will ever be absolutely perfect, since it would require a consensus on everything and everyone understanding the topic equally prior to voicing their opinion. Further, authoritarian beliefs are only true threat to a democracy if majority support authoritarian rule, at which point I would argue it’s not a democracy.
That said, with the advancements of AI, it increasingly dangerous, since if given the tools and opportunity, an authoritarian minority might over take an unprepared majority.
