As I just tried explaining in my reply to your comment's sibling, "direct attack" means "violence", not "name-calling." Anyone who tells you that Islam says it's okay to kill someone for calling Mohammad a doody-head is lying; the Qu'ran has many examples of Allah exhorting Mohammad to remain patient in the face of insults.
"direct attack" means "violence", not "name-calling."
The many many Muslims who called for the death of the Dutch cartoonist a few years back would disagree with your assertion.
I didn't knew much about Islam, but that is serious.
