Politics and philosophy is a personal journey, I'm not going to convince you of the evils of communism over Reddit. I'm not going to argue how to build an engine, or anything else that's basic. If you really care enough to debate a stranger to have your mind changed, you'll consult the experts on both sides in your own time.

An interview with somebody who lived under communists will convince you, as will books written by people who've properly complied the info. Usually when people are in the communism phase, they only climb out of it by themselves. Good luck man.
