What I'm trying to say is that the profile of the US (the general symbol of Westernism in Islamic states) is already extremely low. A lot of people consider the US rude and intolerant; that's just the image that has unfortunately developed.
Ordinary people in those states are probably looking at this and thinking "well this just proves it doesn't it".
I'm not sure alienating people further is a clever idea (us vs. them is one reason why extremism is fostered on both sides).
It's not even really about causing offence (as already pointed out, everyone is offended by someone) but about "proving" to people in those states we don't really understand the problem...
This is pitched as sticking a finger up to extremists; a sentiment I utterly agree with. What it actually is is feeding them ammunition, and potentially causing more resentment in Mulsim countries. I can't help feeling there is a better way to stick that finger up :)
Also; this stinks of fear to me.
