the end goal has caused death and oppression similar, if not worse then, the Nazis
I have extremely strong opinions about this. As someone from a family who was hurt by both, it’s not even remotely comparable. The Nazis wanted my family executed. Communists wanted quiet compliance, with penalties for speaking truth to power. Those things are not remotely the same.
Communism here was not pleasant, fair or safe, but at least you had a set of rules to follow (shut up, go to your job, loudly endorse the official party position, report infractions) and you’d be relatively safe.
This is very different from a regime who explicitly wants to murder you.
