You mix marxism and communism, which is not the same thing. Which do you want to argue?

I consider Marx a clown, and marxism is a clown fiesta, and "capitalism" is the cause they fight against. Of course it contains "meaning".

Communism, on the other hand, is at least a valid idea. Its by no means viable, because its in direct conflict with human nature, survival instincts, intrinsic properties of physics and a bunch of other issues, but as a concept, communism is kinda cool.
