If Muslims or Hindus decided to vocally and loudly worship their god(s) on a flight that I was on, I would not appreciate it for the reason given earlier - you can't leave an airplane when it's in flight.
“No one should be forced to hear the Gospel.” I agree totally, particularly if it’s someone singing praise songs. I can’t even stand to hear them in church.
If I’d been on that plane, I would have climbed out the window. It would be as bad as being forced to hear rap music blaring out of someone’s car.
