Fuck capitalism, I agree. But I don't see where a county with any other economic system was ever chomping at the bit to sacrifice to feed the poorest in the world either.

Be angry, but realistic. Don't fetishize revolutions. Revolutions generally kill quite a lot of people, the vast majority of whom are not members of the ruling class

Ok, so can we agree to do those things without killing anyone who disagrees and then spending a few decades "protecting the revolution" with a "dictatorship of the whatever?"

Subjugating people is a terrible way to liberate them. Full stop. If you want socialism, then the only viable and sustainable path is convincing people to vote for socialism. Which is why tankie extremists are socialism's worst enemy.
