You're in a media bubble. It feels like there's no way anyone could see it differently. The people who disagree with you are also in a media bubble and don't understand how you could believe what you do.
For everything you said they
- don't believe happened
- think it was a deep state plot
- believe it's good actually and believing anything else means you want to kill babies or destroy the economy
- have never heard of it
Reality may have a leftist bias but most people don't live in reality. Most people live in a reality constructed by corporate media. Social media is largely derivative of it.
It's estimated 27 million Russians died during WW2. OP is saying that number is attributable to Hitler. The best estimate given the revealed USSR archives, emigres, and informants puts deaths directly caused or the result of neglect attributable to Stalin is 6.5 million.
Basically the first half of the meme is anticommunist, misinformation that ignores the deaths caused by fascists.
