“Are Russians generically, racially evil?”
I think so.
“When did that start, with Stalin, Lenin, Tsar Nicolas? Peter the Great?”
Russian expansionism started a thousand years ago, from the region around Kiev.
“Was Russia ever invaded and ravaged by Western powers? Or far eastern powers?”
Yes. By the French in 1812 and the Germans in 1941. The Japanese attacked Port Arthur, a leased Russian naval base in 1904.
One could say the same about any European colonial power, and members of their expanding colonies. It’s what we do, It’s what humans do.
