Just curious but if you do not agree with prayer why are you even in the same area that one is being said? You know if there was some satanic worshiping going on i would wanna jump in the middle and "mind my own business". If it is at a table and people want to say grace why not excuse yourself to the bathroom or if it is at a ballgame go to a less populated area.

All i am saying is try to avert a situation at all cost. Whether it is a Christian in the middle of a Satanic ritual or a non believer in the middle of believers. As a human you should try to avert a situation. It is common sense.
