> "communism" can be completely peaceful and nice

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.

By that measure, no political organization can be considered completely peaceful and nice, making it meaningless to say so about communism.

(Excluding full-on no-government libertarians from the above under the assumption that organizing would be contrary to their beliefs.)

[davidhollander]

Yes, that was my argument. I believe it stands until a semantic context for "completely peaceful and nice" can be proposed that is disjoint in meaning from "nonviolent and voluntary".
