Apostasy & Death? I asked Muslims, and most answers were too contradictory to take seriously. Thoughts?

Obama is NOT fighting Islam , he left Islam peacefully that's why you don't hear any one calling for his death , that what shariaa law says , if they left peacefully then no need to kill them but I told you before killing the apostates is not written in the Quran at all so if anyone issues a fatwa for this he is contradicting the Quran .
