1.) You're insane. Seek help. The idea that Barack Obama, awful president that he will be, is a "Marxist Muslim" cannot be held by any functioning, rational human being living in the real world. Seriously, get treatment.
2.) You clearly have no idea what Marxism is. Islamic terrorists want theocratic fascism. They support a religious, oppressive, totalitarian regime led by high priests following Sharia. That is pretty much the EXACT OPPOSITE of Marxism.
Marxism n. the system of economic and political thought developed by Karl Marx, along with Friedrich Engels, esp. the doctrine that the state throughout history has been a device for the exploitation of the masses by a dominant class, that class struggle has been the main agency of historical change, and that the capitalist system, containing from the first the seeds of its own decay, will inevitably, after the period of the dictatorship of the proletariat, be superseded by a socialist order and a classless society.
Origin:
18951900; Marx + -ism
Marxism is irreligious, leaderless, egalitarian. Everything Muslim extremists don't want.
What's wrong with them wanting theocratic fascism? That's what Republicans want for us too.
