You made it about communism by complaining about tankies
From Wikipedia:
Tankie is a pejorative label generally applied to authoritarian communists, especially those who support or defend acts of repression by such regimes, their allies, or deny the occurrence of the events thereof.
Not about communism as a political philosophy.
You are covering up the ethnic cleansing committed by Kiev against the Donbass region
This is a common myth created by Russian propaganda. I invite you to check it for yourself. Open an official website of any town that was part of Ukraine before 2022 and had Russian majority in population. Check publications before 2022. You’ll see an abundant use of Russian language and culture. Even Zelenski, with Russian being his first language, often spoke it in political campaigns.
Now many of these towns are ghost towns due to shelling.

Never heard it used against democratic socialists who acknowledged mistakes of the past.
So you believe there were no authoritarian socialist states in history? Ones that silenced critics, shot protesters, censored press and didn’t have competitive elections? Lol.
This war killed almost half a million people already on all sides combined (if we believe Russian MoD, this number way exceeds a million). Do you think the “ethnic cleansing” would kill this much in a thousand years? According to DPR-operated media, only 17 people died in last years before 2022 on Donbas, most from uncleaned minefields.
