I think what Quagmire showed us here is interesting and shouldn't pass easily.
It's amazing that you couldn't apply this to yourself. As long as this concerns other people, "I don't give a damn" but when it comes to you, you whined like them. Not only this but you hinted that you want to report the person who didn't "accommodate your fragile sensibilities" and to ignore him as well.
Now if you asked me I would say that you don't have a sense of humor; I thought what Quagmire said was funny and you were overreacting and acting irrationally.
I have noticed this many times, that the same people who sarcastically wonder "oh, why don't Muslims have any sense of humor?!" and "why are they whining like this?!", can be easily ****** off, for silly things but the main difference that such persons don't have a sacred figure in their lives except maybe themselves. So when their selves become confronted with what might be offensive, they get really angry.
I don't blame any Muslim who thinks that he (or she) want to boycott Facebook or ask for the removal of such empty hateful groups because as lava says; it's a human thing.
True, that sometimes there is unacceptable behavior coming from some Muslims but I can understand it as well. Because it's not about drawing Muhammad only, it's about the invasion of Iraq, it's about supporting Israel unconditionally, it's about the minarets ban, hijab ban, etc.
I think you have made two amazing points here:
1) That some of the people supporting this couldn't stand anything near what they are supporting, if it is done to them.
2) That making such groups and episodes about Muhammad (pbuh) in the middle of all the problems we have today, is rather childish and provoking.
