But this fact is touted as its USP, I have not heard of other religions crowing about 'peace' so much ! 
There are enough fools to fall for it though.
Heard about Jainism? Why aren't people drawing cartoons about 'Lord' Mahavir ?Even if someone were to draw a derogatory cartoon I am sure he wouldn't be killed for that neither will his coreligionists be harmed.
 There is a serious problem with Islam Hypo-C..  You see if you take the names from that list of religious figure heads written in that   Michael Hart's book   
 "The 100: A Ranking of the Most Influential Persons in History," you have this list., there are 20 or so religious figure heads and Number one comes out as  "Muhammad"
1    Muhammad    Islam
3    Jesus Christ     Christianity
4    Buddha            Buddhism
5    Confucius    Confucianism     
6    St. Paul            Christianity
15    Moses             Judaism
17    Shih Huang Ti    Chinese traditional religion
18    Augustus Caesar    Roman state paganism
21    Constantine the Great    Roman state paganism; Christianity
52    Calipha 'Umar"    Islam
53    Asoka    Buddhism
83    Mani    Manicheanism
87    Cyrus the Great    Zoroastrianism
93    Zoroaster    Zoroastrianism
96    Menes    Egyptian paganism
98    Homer    Greek paganism
100    Mahavira    Hinduism; Jainism    founder of Jainism 
 So if you write a page on each one of them about their good and bad deeds from the earliest books of their followers..  Muhammad and Omar comes out as bad guys..   
So This is in-built in to Islam ., Muslim know that these guys were bad.  And it is well known human reaction.
"
 if you call a good guy a bad person, he and his follower don't care., but if you call a bad guy a bad guy, he and his followers beat you up.." That is exactly the reaction we are seeing since beginning of Islam. So the reaction you see from Muslim guys is unexpected., it is a human behavior. 
No doubt that is STUPID MOVIE by fools what kind movie uses dialogues  like these?? 
Servent of Khadija: "Muhammad the bastard your lady calling you."
Lady eating some  bone:   "  yes  bastard Master Muhammad'
Muhammad:    what did you say glutton..
Lady eating some  bone:   "  sorry   bastard Master Muhammad'
clearly these are fools.. with foolish dialogues., But Muslim also  realize that in those dialogues some of the   stories of early Islam  that come right out of Quran and hadith., Such as killing of that old lady., Muhammad marrying 6 year old girl or killing those 800 Jewish folks of the town or Muhammad marrying his adopted son's wife and banning adoption in Islam ..etc..etc.. 
Here they have no way of defending it neither laughing at them as stupid jokes because you see those jokes in Quran and hadith..  
So the problem lies there...., Some one takes that same movie, same dialogues 
 but replace the word "Muhammad " with "Christ or Moses" and put it on web.. NO BODY CARES.. people will laugh at such silly movies/tubes 
because you can not get such stories  on the lives of Christ and Moses out of OT or NTI tell you this., 
 if you live around Mormons and talk Prophet Joseph smith and his wives and concubines  and insult him, Mormons will beat you up., because  there is some truth in it..The only that is left to Muslims is ., LEARN TO LAUGHT at such movies and wherever it is possible
 "EDIT QURAN AND BURN HADITH"  otherwise in 21st century with inexpensive technology and free web, they   will be watching lot more such movies.. 
That is a very good response on that movie hypo-C..
