Nice ad hominem bro.
I have family from eastern europe. I also have family from east germany.
You know what they say? You know what the majority of the people who lived that era say? Its much worse now.
People using stalin and national socialism to discredit the idea of communism and socialism need to start reading books. Its really important to start having actual discussions without personally attacking folks. These shortcirtuited propaganda ridden hateposts wont convince me and they wond convince anyone who is able to read a book.
People in eastern germany, infamously, didnt have bananas most of the year. You know what they also didnt have? Homeless people, starving people. Today that is the case A LOT.
Of course it was interesting and promising for people to come to western germany from socialist or communist countries back then. But its not because they had to fear for their lives because they couldnt afford to pay the rent or their food.
The most important part is that authoritarian governments are not what leftism is about, its not what socialism or communism is about.
Here's interesting stuff from a pretty reliable source: https://en.m.wikipedia.org/wiki/Red_Scare
Have fun reading. It will help.
