Leenia: I really dont think you have the right to decide who is and who is not a Muslim, according to some criterion of your own. As a general rule of thumb, if someone tells me they are a Muslim, I reckon they are Muslim. If someone claims to be an atheist, I reckon they are atheist. Of course, they may be lying, but in generaL I think we can define our own religions. You seem to be saying that a sinner cant belong to a religion. That is not a generally held belief, I think you are in a minority there.
