I don’t see many central European states killing people for the reason of having different ideologies these days. And if they did their leaders wouldn’t be celebrated for the books they wrote.
Without any kind of repressive system you’ll have anarchy.
Well I compare the extreme left with the extreme right since it is basically the same imho. Different reasoning for the mindset of “what’s not with us is against us”.
Communists committed the same crimes as the Nazis so of into the same cell and the key is best disposed of.
And the other big problem with pure socialism:
Why hasn’t it worked yet? No Utopia as of yet, only repression, human rights violation and death.
It’s as if the human factor is the point where there is change needed, not the system itself.
