Not that I'd care to throw out a blanket justification for any and all anti-Communist measures out there, mind you. But it's possible to downplay the threat excessively too.
Perhaps some forms of Anarcho-socialism could be argued to be both completely nonviolent (peaceful) and voluntary (nice). However any form of Communism calling for the abolition of capitalism, which asserts that others do not have the right to continue asserting claims to private ownership of capital independently, most certainly cannot be considered either.
