socialists and Marxists get accused of being deterministic but if we look at history, through the decades capitalism is integrating socialism into it. I think at some point it will simply be socialism. We’re just not there yet, I think that won’t happen until human labor has no value.

A few points: Capitalism hasn’t freely integrated socialist ideas. Each idea has been won through workers’ struggle. Even after the fact, those wins are clawed back by the capitalist class. They will capitulate as a means to defend against revolution—which flows back into your Zizek quote: capitalism’s way of reinventing itself. But capitalism, as a political philosophy, will always maintain a ruling class and an underclass to exploit.

This is why we must continue to struggle, and why we should not see these small capitulations as proof that socialism will evolve naturally from capitalism.

PS: you would probably enjoy Leon Trotsky’s writings. One book he wrote: Fascism, What is it and How to Fight it. Where he takes a principalled and dialectical approach to the subject.
