I have participated in a lot of debates where the other side would always quote the bible to defend a certain thing's morality. It sucks, because we all know how illogical it could always be when one uses such argument, plus when you want to make a purely rational point that could keep everyone regardless of religion listening, that whole misuse of religious stuff just gets in the way and automatically makes the people even the panelists (damn, here in Philippines they're always religious) side with them. It's not fair in the event of civil debate.
