~1.6B people consider drawing Mohammed to be a blasphemous action. That's not self-defense; that's antagonistic.
Edit: I mean, if they had been asked nicely I would totally agree with you. But it must be made clear that threats are not an appropriate way to deal with religious issues.
But what result are you (or Mohammed Doodlers - "MoDoods"?) hoping to achieve?
And will antagonizing militant muslims help achieve that goal?
Edit: the point is you're antagonizing waaaay more (likely on the order of 1 billion or more) than the people you're trying to, which is counter-productive.
