An interesting observation after traditional Christmas arguments with my right--wing relatives in Poland:
Alt-right is now talking 100% postmodernism.
History made full circle: half-century ago it was mostly far left who ranted about "gender aspect of mathematics" and "science as a social construct", basically denying humans ability to objectively describe reality.
These tools were initially forged by Marx to facilitate his wishful thinking about how societies operate that science did not support.
In 20th century far-left faced the same challenge and picked the same tools as they knew them well due to ideological compatibility and general inspiration by Marx.
Today the same Marx-inspired tools are being picked up by alt-right generation that talks about "evils of cultural Marxism" (a bullshit term on its own).
Sokal Affair was LOL, this is LOL squared.
Probably the most prominent example of this attitude of Marxism was the rise of Lysenkoism and subsequent prosecution of geneticists in USSR - a conflict that originated specifically from rejection of the idea that a fundamental change in nature could be a result of a random mutation in individual organism, a concept fundamentally incompatible with Marxist ideals.
@kravietz Marx was not a Marxist. And I mean that literally, because Marx said he was not a Marxist. I do not think what happened in the USSR, especially under Stalin, has much to do with what Marx wrote about also. So while the prosecution of geneticists may describe Stalin's reign, it doesn't really have anything to do with Karl marx.
