The problem is that you do not know what you're talking about. Your idea of communism is a liberal one and not one born out of material analysis.

You also do not know what "communism" and "communist" means, adding to your confusion. The first is a stage of development, it can't be reached over night, but only via a multi generational process called socialism. The latter is a type of socialist, a revolutionary and scientific socialist to be precise.

Being a communist does not mean that you think communism can be reached on a drop of the hat. It is someone who knows that reformism is impossible and going straight to communism also. Someone who knows that stages of development transform into each other. As such they bear the birthmarks of their origin, these can not be spelled away but have to be carefully removed over time, with the initial generation not even seeing most of the marks as such because it has been too accostomed to them. For further reading I really recommend Lenins "State and Revolution" and Engels' "Socialism: Utopian and Scientific". They are not big books and enjoyable to read.
