LOL Muck!
I think its fine to bash islam in general. Mockery makes a muslim think about things they never would have questioned before. I know I did. But when it comes to individual muslims, mockery only drives them away. The idea is to mock them and knock a piece off the islamic block, then draw them in with your side of the story. At least for me, this is the most effective way.
and FTF, I'm not laughing about islam, I'm really just laughing at the wit.
