GPP is irreverent and snarky, but it isn't in the least mean-spirited, and this "crusade" most certainly is.
(Of course, it's in "defense" of one of the most mean-spirited shows in U.S. television history, so yeah.)
This little stunt offends me because it's not just aimed at the Fundamentalists; this is a deliberate slap at moderate and progressive Muslims, as well (not that many of the Draw Mohammed Day crowd actually bother to acknowledge that there's a difference). It's a wide-sweeping smackdown of an entire group, and it's saying the same damned thing that the real offenders keep saying: "all of them hate all of us."
Gods damn it, people. how hard is it to grasp? If you're really opposed to an ideology, don't let its adherents frame the argument.
I'm not saying "don't do this". I'm not saying "it shouldn't be allowed". I am saying that we need to examine the motives and sincerity behind it. So much of the output is a tedious repetition of hackneyed Prophet-As-Terrorist memes that it's hard to see it as a statement of "artistic freedom".
If this were really about "free speech", we'd be following it with "Draw Christ Getting Raped In The Nail-Holes Day".
Wow. I think that's the most Regrettably Appropriate use of the word "crusade" I've invoked in a long time.
