I went to Catholic schools 1-12. I had a grade school friend who chose to go to the public high school. In those days (sixties) most Catholic kids went to the Catholic hs and most Protestants went to the public high school. After Kennedy got shot, one Protestant kid, who I also knew, danced down the high school corridor shouting with glee about how happy he was Kennedy got shot. My grade school friend punched him out. Considering the level of anti-Catholic feeling still prevalent in the country in those days, I'm sure there were more than a few fist fights in the wake of the shooting between different religious parties.
One of my best friends in high school was Catholic. His family and the girl I mentioned were the only two I knew. They were a bit of a curiosity but no one hated them or wished any bad will towards them.
The girl I mentioned had a Polish name. The county I grew up in, Walton County, was nearly 100% descended from Highland Scots from the Western Islands. Even as late as 1960, well over half the population had Scottish names.
The tiny Catholic Church is named St. Margaret of Scotland.
