The problem is reverence for the Prophet is non-negotiable.
Non-negotiable means direct conflict.
Islamics are allowed to insult the Pope, insult Christ (to most Christians by disavowing his divinity or that he was crucified) yet, anything seen by them as insulting excuses murder.
Over and over we are seeing comics or speeches about Islamic violence produce Islamic violence.
Then we have people in the West excusing such behavior. It's inexcusable.
Murdering a anyone because of what someone else said cannot be excused.
