That's the most gish gallop I've ever seen crammed into a single sentence... I've given up writing rebutals to the 8 different tangents, insinuations, conflation, etc. and will instead focus on a single point:

Every single ideology will say their opponents are responsible for countless lives lost. (And if they lump everyone who disagrees with them together can probably make such a case) Just for an example, capitalism vs communism. I'd rather not be stuck in a China like situation where arguing against government beliefs like "this new virus in Wuhan is nothing to worry about citizen" gets censored or we get eternally stuck in a suboptimal state because arguing for anything different is considered dangerous.
