You're right the Prophet did not take revenge for himself because his concern was how to get the ppl away from paganism not how to assert his own dignity.

To us it's more emotional.. WE cannot tolerate to see him wronged or described in a hateful way..

that's why I opened this thread.. Note the language I used; "kindly requested", "Thank you", "Please" "I understand"..etc. However it's still not good enough to those religion-hypersensitive!
