I personally know people that endured the UDSSR. And those stories are not pleasant.
And seeing the anti capitalistic movement being accepting of radical ideas and the idea of using violence and the belief that the vote of the masses (who are in favour of Capitalism) is unimportant, just makes me believe that anti capitalistic movements all strive for what we saw in the UDSSR and today in China.
I only accept political ideas that have been viable for years in other countries without the occurrence of dictatorship. If you are a US citizen, then the wishful view to Western Europe is the only one I’d accept as reasonable.
And as a Western European myself, I can say that even though we currently face massive problems with immigration, life here is still more enjoyable than in the rest do the world.
