I went to an Episcopalian parochial school for 6 years where there was a mix of kids from all walks of life. I was taught to respect others beliefs as I would like them to respect mine. It has worked well for me in many aspects in life other than religion. One did not have to agree or accept another's belief but as long as it wasn't directly injurious to others, giving a little respect never caused me lasting harm.
That pretty well sums it up IMO.
