And do you see anyone on this thread who claimed otherwise? This isn't about denying Muslims the right to practice their cult (as long as it doesn't involve violence), this is about the President shamelessly pandering to that cult.
Perhaps I missed it, but I can't recall the President celebrating Rosh Hashanah in the WH last month. ...or any of the Hindu or Buddhist holidays.
The Muslim, Jewish, and Christian faiths happen to be most prominently practiced by our citizens. I would not expect the President to observe or honor every religious sect.
