And Mendelian genetics wrecks the party with the unhinged liberalism of accurate science supported by half of Pavlov's students?

In the beginning of the USSR, there was legitimate struggle against bourgeois science, like race science. Genetics was unfortunately overly combatted in the crossfire. The USSR was still far more dedicated to scientific pursuit than Capitalist Countries, and managed to get a man to space before even the US.

As for your books, you may realize that I am a bit short on time and do not have the energy to read 4 entire novel-length books instead of specific pages or chapters.

Then just read Blackshirts and Reds. If your time is so short that you can't read even 1 short book on the topic of dispelling myths about the USSR, then your time is too short to argue with people online about it too, no offense. Blackshirts and Reds is recommended reading for new Marxists in general because it's short and to the point, and written in common American language without requiring having read books and books of Marxist theory to understand.
