This response allows you to view people who believe differently from you as people, too: they were simply brought up to believe different things. They are no worse and no better than you are, just as you are no better or worse than they are. By your standards, you have the superior morality, but by their standards, you carry the weight of inferior teachings. If you can both set these judgements aside, however, and treat each other as humans first, then you have a bridge; a place to start understanding each other.
