I reinstate my previous point that Muslims have a double standard in this matter.
All Prophets, whether they be Jesus, Moses, Ibraham etc. deserve and demand the same amount of respect as Prophet Mohammed(s).
Muslims do not grant the same level of respect because of their idol'ism of Prophet Mohammad (s) and the disavowal of the all our other Prophets. While it is true that Prophet Mohammed is the last of our Prophets, why don't Muslims mind when GOD and Jesus or Moses are portrayed in movies when they deserve the same highest level of respect?
It reflects a disorderly mental state of ummah, which you mentioned as N2ism.
