Communism, fascism, socialism, progressivism, etc., are all forced collectivism.

Voluntary collectivism is not the same thing. Do ants work of their own free will?

In voluntary collectivism people can choose whether or not they want to participate. They can join and leave any time they want. They get to own private property. They only give their excess to the collective, keeping what they need or want for themselves first. Everything is voluntary. It's all based on freedom, charity, and love.

I know. Sounds very hippie, but what I described is a Mormon system known as "The United Order"
