I think Comunism is very bad for citizens of any country. People loses their freedom and become stupid zombified sheeps. Comunism in some sence is a sort of religion in my opinion. Examples are North Korea, China and USSR
It's not only what you think, it's a fact. They are the cause why people have a lack of independence to live free. Sadly, it is impossible to unleash 100% of them because they we armed and if ever some of them were killed, they can influnce others to go against the peace which is what their side.
