Yes, that would be the sensible response, and one I'd imagine to make sense within Islam too... A better response than reacting to insinuations that Islam is a violent religion* by calling for the "massacre" of all who insult Mohammed... You'd think the logical error would stop anyone in their tracks, but not so... Ah well, people are the same the world over in this** respect...

* This being the gist of the 2 out of 12 that are offensive (offence above and beyond the depiction of the Prophet, which surely a logical Muslim can't expect non-believers to hold as taboo...)
** Glaring irrationality.
