I fully endorse the mockery of religion, especially larger religions that expect people who do not share their beliefs to pay attention to their silly rules. Disallowing people to draw historical figures, like Mohammed, is an idiotic rule. If you like the rule, don't draw him. However I will:
This is my rendition of mohammed with his ceremonial blade, just after he hacked off one of his wife's head after giving a sermon of how peaceful Islam is.
P.S. I am fully aware that my rendition of Mohammed looks like an Amish serial killer. I never said my artistic skills weren't outdone by a 3rd grader.
