I grew up in Ohio in late '80s through the '90s. My parents, sisters and I were one of the few South Asian families in town, and I was one of only two Hindu students in my graduating class of nearly 350 students.
Fortunately for me, it mattered little that I was Hindu and most of my classmates were Christian. I can't really remember any time the school brought in religion -- a rarity I appreciated living so close to the Bible belt.
But had I been in sixth grade in 1962 rather than 1992, things might have been different.
