Religion was sold hard in Dixie in the 50s and 60s but I wasn't buying. Our public school would have traveling evangelist visit the school to preach to us and demand attendance by the whole school. We did the Lord's Prayer every day before class right before the Pledge of Allegiance. I don't think that there was a Catholic or Jew in the school, certainly no Muslims, but there were no Asians, Blacks or Hispanics either; we were Lilly white. 
A very common question, in that time, when you were being introduced to someone, was,"What church do you attend?" I still get that every once in a while now. I just answer, "I don't and have to deal with putting the poor soul in a state of shock. Seriously, I have had strangers gasp getting that answer.
When I went into the Navy I had to select the religion that I practiced. They let me know, in no uncertain terms that none was not an option. (1971) if killed, I would have been buried as a protestant. I think, but am not sure that my dog-tags had Methodist on them. There were no atheist in the Navy in the day.
