Can you point me to the exact sentence where I trivialised the holocaust? Hint: I didn't say anything about the holocaust. All I gave you is a link, the rest is your imagination.
You, OTOH, are severely trivialising antisemitism within the USSR. Stop fucking fanboying.
pre-soviet monarchy backed by western liberal democracies
Please fucking what liberal democracies during Tsarist times? England, France, possibly, am I missing one? And none of that antisemitism was home-grown, it was all the fault of those evil foreigners making poor Russian nobles and priests do stuff? The country most busy with fucking with Tsarist Russia, specifically sending Lenin over mind you, was Germany, very much not a liberal democracy. The age of liberal democracies started after WWI.
