I was just in a Muslim country. Was on a total of 4 planes throughout my trip, 3 of which I know for a fact were flown by Muslims, and didn’t have a single problem.
Everyone I met in the country was incredibly nice, and didn’t mind that I practiced a different religion or didn’t abide by their religious laws (as long as I didn’t break the laws of the country (sometimes they are one and the same, in this case they were not).
Food was good weather was great and all in all I’d go back in a heartbeat.
Also, your flight 804 story is fake, hate inducing clickbait. There is zero evidence of anything stated in that article you linked above other than the plane crashed.
