In many ways this harmed the formation of socialist opposition within many countries, as marginalised sections of the Proletariat, instead of rallying around the communist party, where forced to instead align themselves with the liberals.

This also acted as a excellent tool for western propaganda, as many anti-western states in eastern Europe, such as Ukraine (up until Euromaidan.) Belarus, and Russia, often embraced highly conservative and reactionary cultural traditions, which in turn made it easier for the west to delegitimise socialist groups in eastern Europe.

I completely agree. Reactionary positions on social issues are self-sabotage on the part of communists. They make forming a united working class movement more difficult and give propaganda ammo to the liberal-imperialist enemy.

Also, excellent breakdown of the 2020 color revolution attempts in Belarus and Russia!
