Capitalism is a useless world because few people understand it the same. The supremacy of capital owning class is the most common understanding of both pro and anti Capitalists.

But Capitalism is originally defined as free and fair markets, and so against Supremacist corruption of markets where the counterparty negotiation class is necessarily oppressed.

So exterminating all government politicians, and nationalizing all of their donors’ assets is the real proper interpretation of these domestic terrorists. But a bigger problem than intending the opposite, is that it is subject to absolutist expansion of supremacism. Refusing 16 hour shifts, or corporal punishment authority granted to your managers, or not letting a better richer capitalist destroy the land/property of a lesser poorer owner becomes anti-capitalist when Fox news tells you it is.
