"mathematising" actually gave an example of communism, which he defended, as lenin's communism (which was basically the standard model of communism for those other dictators)
you're saying "communists" like "mao, stalin, etc" as if they weren't "communists", yet the OP of that other thread would have had to have thought of them as communists because they specifically rejected anarcho-communism to me in favour of marxist-leninism - he even said he'd be fine with an authoritarian leader so long as the revolution would happen (paraphrasing)
PS: the link with those figures isn't actually suggesting that it was *capitalism* that cuased deaths, you're saying it was the problems or actions of the respective governments of the relevant nations that caused the deaths. for instance, "belgian exploitation of the congo" - how is that capitalism killing people? that's kind of the opposite of capitalism killing people - coercion. capitalism is individual activity done *without* coercion.
