You're really taking an overly broad and negative reading here. The commenter you replied to obviously referred to the current U.S. administration when wishing for them to take orders from Russia. The joke being that the alleged conspiracy would have a favorable outcome compared to the bumbling response we observe. The comment doesn't suggest (at least to me) that this should be a general policy. Similarly, calling conventions disastrous during the current pandemic is well in line of discourse about limiting the spread. Interpreting this as "a plea to end democracy" overinterprets things much. Is a democracy really a democracy if it is so fragile it could cease to exist when a few conventions cannot be held? Please show a bit of good will when reading others' comments.
