All across the Muslim world, Muslims are being oppressed - either by other Muslims, or by Non-Muslims.
Even in places like Turkey the hardcore ultra secularists are still just waiting to get their revenge on the religious people who currently have the power.
Palestine is always an easy cause and it has been going for a long time. The people need resolution.
But unlike before when the Arab street at least felt sympathetic, that seems to have changed. Instead of the leaders making atleast some statements in support of the Palestinians due to fear of the people, the people too often support their dictatorships against raising any voice.
