It’s perfectly fine to use “whataboutism” to counter tired talking points that do nothing to advance actual discourse. Like yea, people died in capitalist countries too, how is that in any way advancing a discussion about these differing economic systems. Go a step further, ask why these things happened in communist countries. Think about how they differ from similar situations in a capitalist country. Engage with the ideas and then we can have honest discourse.

It doesn’t mean literally eat them…

Look, I won’t argue with you on semantics. You’re free to disagree with the common definition of liberalism that socialists use. It’s really just a convenient term for people that are pro-capitalist. It’s not intended to be a nuanced term, and I doubt most reasonable socialists would directly equate Republican fascists with Democratic progressives, even if they see both as problematic.

That’s fine, just understand that you’re using a US-centric framework that differs from what socialists mean when they say “libs”. From our perspective, if you’re pro-western-capitalism (and thus pro-neoliberalism) you’re a lib. Democrats, Republicans, doesn’t matter.
