i'd tweak this a little bit, in investing more effort into separating between mlms and communists. i'd identify as both an anarchist and a communist, but not as a marxist (despite citing marx fairly frequently) and certainly not at all as any kind of leninist or maoist. nihilism is likewise a complicated term, and the author is actually using it wrong, here; i would certainly identify as an existential nihilist, while rejecting colloquial uses of either term.

but, i think this gets an idea across.
