Often they will defend themselves saying that they are not Communists. Nope, everybody knows Communism does not work. They are Socialists. Much, much better than Communism, that.
My curiosity piqued I looked at Wikipedia to tease apart the differences between Socialism and Communism. This is what I found:
The words socialism and communism eventually accorded with the adherents' and opponents' cultural attitude towards religion....In Protestant England, the word communism was too culturally and aurally close to the Roman Catholic communion rite; hence, English atheists denoted themselves socialists.
So there you have it, in English speaking countries Communism and Socialism is identical except Socialists only hate Catholics while Communists hate all people who practice religion.
I hope this was helpful.
