I don't think anyone really cares what other people believe and how many times a day they pray or stand on their heads, whatever their god tells them to do.

The point being very clearly made which you seem to have missed is that any negativity against anything to do with the religion of Islam is seen by a lot of their leaders and the crazies that listen to them as a reason for violence and murder as evidenced for example by the Fatwa to kill the author Salman Rushdie and the murder of the Charlie Hebdo employees. Even ex muslims speaking out against Islam have targets on their heads!

I could be wrong but I don't think there is another main stream religion on earth that has leaders that order killing of another just because, in their opinion, someone has blasphemed against their religion!
