It's amazing how quickly humanism slips into quasi-fascism in the name of justifying racism as some kind of "human nature". Good evidence of why humanism deserves to be a swear word rather than the current "yay" concept it is, on a par with democracy - "human nature" has always been used to exclude those who don't fit the "human". The flip side to the human is the inhuman.
And if you don't want us to call you a racist or a fascist, don't justify this abhorrent shit that even a passing knowledge of biology or sociology would quickly debunk.
“Socialism cannot abstract itself from individual interests. Socialist society alone can most fully satisfy these personal interests. More than that; socialist society alone can firmly safeguard the interests of the individual. In this sense there is no irreconcilable contrast between “individualism” and socialism. But can we deny the contrast between classes, between the propertied class, the capitalist class, and the toiling class, the proletarian class?” - Josef Stalin, Marxism Versus Liberalism: An Interview With H.G. Wells, 1934
"Those who are in ideology believe themselves by definition outside ideology: one of the effects of ideology is the practical denegation of the ideological character of ideology by ideology: ideology never says, ‘I am ideological’." - Louis Althusser, Ideology and Ideological State Apparatuses, 1969
