The President seeks to appease a religion?!?

Why does our President feel it necessary to appease a religion, to meet with leaders of that religion, fly to nations with majorities of that religion, and have long, extended speeches specifically to speak to members of that religion?

He flew to Egypt to speak to "the Muslim world". Not the Arab world, not the middle eastern world. The Muslim world. Did he fly to Italy to speak to "the Catholic world"? Did he fly to Israel to speak to "the Orthodox Jewish world"? Did he fly to Germany to speak to "the Lutheran world"? Did he fly to Japan to speak to "the Buddhist world"?

Then why select one specific religion to speak to? Repeatedly? And specifically to apologize to them? On two separate world tours?
