Communism vs. Islam

[JohnFKennedy]

Before I'll answer this I wanna know two things:

1. What do you mean by Communism?
2. What do you mean by Islam?

dictionary definition.

In other words you are asking which is better in theory?

As dictionaries do not define what happens in practice, we can effectively throw every communist and Islamic temporal regime out of the window and look at the two on principle.

On principle both are actually quite good though Islam is generally the more misunderstood.
