Of course you are not an Atheist Gaffer, Only a religious person of an opposite faith would be likely to have a viewpoint such as yours on the muslims.
I am a functional Atheist. I do however support True Christians as they are good people and not haters. Jesus was not a hater, and one definition of christian is to be Christlike. He taught peachful ways and tolerance of differences. Now where I divide from Christians is that I don't believe he was the son of god. But he brought peaceful ways to turbulent and violent times.
the old testament now is an entirely different story.
Just my opinion though.
