You can indeed describe something as incomparably worse when it is so bad that a comparison doesn’t make sense or there’s no point to making one. I really don’t think I’m the one who’s out of line here.

Anyway, the whole “victims of communism” trope you’re invoking is just embarrassingly facile. The numbers are contrived and no consideration is ever given to the terrible conditions out of which the various revolutions came or the horrible forces they were subsequently up against, let alone comparative conditions in the so-called free world. Everyone who ever lived and died in a communist state is a crime against humanity, but whenever someone dies in the US because they had to choose between medicine and rent it’s their own damn fault. Give me a break.
