Interesting points, but do you think you are going to change the attitudes of many Muslims by drawing Muhammad?
I don't think the intent is to change the attitudes of Muslims in general; only those who would use violence to suppress free speech... and I think the attitude change that the campaign aims for isn't to make them think that pictures of Muhammad are inoffensive; it's to make them realize that violence will be ineffective for achieving their aim.
... or, in a more general sense, it's to make them realize that their intended goal of suppressing free speech will be impossible.
Which persons? I doubt that the average adolescent taking part in the Face book fiasco is putting themselves in any danger.
Yeah, they're probably pretty safe... just like the thousandth person to jump up and say "I am Spartacus!" Still, I think that even if they experience a low level of risk themselves, this doesn't mean that they can't intend a message like "I will do this even if it's risky" behind it.
Also, their involvement serves a purpose: another big part of it is simple amplification. If the guy who attacked Kurt Westergaard, for example, realized that the net effect of his attack would be thousands more Muhammad cartoons than would have happened if he hadn't attacked him, maybe he'd have been less likely to try the attack in the first place. That teenager safe in his room in the Midwestern US is still part of those thousands.
When the people who came up with the idea in the first place realized they could wind up at risk they backed out.
All the more reason not to stop now, then. If the people that threatened the originators of the campaign learn that they can get their way through threats and violence, this will be encouragement to them and others that the tactic is a good one.
A lot of people are trying to paint the whole Draw Mohammad Day thing as some sort of political activism. It's actually re-activism.
It's a reaction to violence and threats of violence, yes. I don't see how that's a point against it, though.
