You certainly took that the wrong way. My point is that any sort of unusual behavior is suspect on planes these days, and drawing attention to oneself in such a manner will get you special attention from the flight crew. Talking loudly about the world coming to an end would put a lot of people on full-pucker alert, and if the passenger didn't follow instructions to go back to his seat, but just went right on walking up and down the aisle testifying, he could expect security to meet him when he disembarked the plane, only to be charged with interfering with or not obeying the instructions of the flight crew.
I did not in any way, shape or form try to establish moral relativism between Islam and Christianity. It's so obvious to anyone here the difference between Christian behavior and that of the Islamists, I figured I wouldn't insult all the intelligent people here by pointing it out.
