I don't see the big deal here, I doubt he hates Islam/Muslims, and is just having fun with instagram or friends. It doesn't offend me, it's just a picture. The more immediate concerns for the people in that region should be the state of the region, and the instability in it. Also spreading religion for influence/business purposes, through many clerics, some overseas, to keep influence over them, not allowing Muslims to evolve. Countries like Saudi Arabia, unfortunately pour lots of money in the West to fund scholars to teach the youth certain teachings, keeping them in line with Saudi Islam POV, and also political POV. They leave many Western Muslims with identity crisis's, some of them become Salafist. And that community which should be a more Westernized community that can be so capable, no longer gives off that image.
So that should be more important first, these countries, Saudi, Qatar, Iran, etc... need to stop trying to influence Muslims in the West, with teachings they don't even follow, and world views that are not compatible with reality or Western culture/ideology. All for the sake of trying to be more powerful by using religion for mind control on millions of people. That is much more disturbing than this photo that was done for fun or being childish.
