common propaganda about communism , marxism and socialism

The people that I talk to about communism don’t really know what it is all about and there is a lot of lies about it. i was wanting to know any propaganda you know of and a source of why it is wrong.

Communism is idea. Some communist governments are good (like Yugoslavia and Cuba) and some are bad and corrupt. A good communist government is that their leaders are competent, truly compromised with communism, the quality of life improves and the government relies on popular support to remain in power.

A bad and corrupt communist government is that their leaders are corrupt, the quality of life falls, and government relies on military power rather than popular support to remain in power.

I believe that Western propaganda is based on bad experiences like Camboja and Ethiopia.
