For the record, i never claimed anything beyond that the public opinion changed over the years, likely because of propaganda. A lot of factors were at play, including the neverending resistance by good people, both in the Reich and occupied territory, the categorical extermination of educated people that didn't subscribe to the Nazi believes and more. Summing everything up to be because of "n" has always been incorrect.
Which is why I didn't attribute truth to either of these claims, instead I pointed out that the USSR would've likely taken over Europe without the direct involvement of the USA, i don't think that this is controversial at all, or do you believe they would've stopped in the middle of today's Germany if they weren't forced to?
Beyond that, Nazis are hardly vilified, because they're literally villainous. Please remember that Nazism isn't National Socialism, what the Nazi regime was based on. It was one specific version of it, which includes mass murdering vast amounts of people. You can make an argument that national socialism isn't necessarily bad, but doing the same for the Nazis means you also condone mass murder, as a simple example: exterminating queer people and people with disabilities was core to their doctrine.
I'm utterly at a loss how I'm supposedly ignoring the crimes of the USSR. Would I have been glad that the USA protected Europe from it if I considered them faultless?
