Other religions weren't even discussed in my elementary..and if they were, I have no recollection of it. I went to elementary in the late 70's, early 80's. I recall it strange if you were christian but not a Catholic. It seems the catholic schools back then were more prejudiced against other Christian sects than they were Judiasm or something else. I recall the horror on the kids faces when we learned those Protestant priests could marry!! Oh the horror! lol
I'm not making fun, btw...I'm just reminiscining. I still think the education in parochial schools are superior than public...and that's what counts.
