It's true some ideas are dangerous but I don't think it's a bad thing to try to understand what is communism, what is capitalism, what is socialism. Who created them and what were their intentions? I thinks in simplistic terms it's a scale with capitalism at one end socialism in the middle and communism at the other. Capitalism is the individual is more important than the mass. So each person is out for themselves vs. communism (as intended) where the mass is greater than the individual. Everyone works together to improve their fair. I like socialism. You have the capitalist market so people can better their fair but also a protected part, such as police, hospitals and education that help everyone have an equal start and are prepared for making it in the capitalist market.
