When I was a young girl growing up in rural New Brunswick (mid - late 70's) we had a old county store just down the road from us. My friends & I would go there on Saturday mornings with our pocket money and spend on penny candy, you could get 3 green leaves for a penny or 5 cinnamon jelly beans for a penny ect ect. My favorite was "nigger babies" (little pieces of black liquorice shaped like a baby).
That was the actual name of the candy, not a name us kids had made up. You would ask the shop keeper for 3 pennies worth of nigger babies,2 cents worth of green leaves, and 2 pair of lips...there would be your 10p spent (lips were expensive!)
As far as ethnic miniorities go, every single kid in my junior high and high school was caucasian, there simply weren't any other races of peoples living within the 40 mile radius of the school to sent their kids to it. (we ALL traveled to school on school buses, one friend of mine lived over 30 miles from the school)
Anyway, when we asked for the candy, we had no idea anyone would ever take offence at it, IIRC the name was changed in the 80's to something like liquorice babies.
What we did have was a whole bunch of different relegions...funny enough no Mulsim or Judaism though. Nobody ever chummed around with the Pentecostals, who were all easy enough to reconize with the girls only allowed to wear skirts or dresses and the kerchiefs on their heads, there were a couple of Seventh Day Advetists, & 1 Jehovah's Witnesses everyboy chunned them because their religon was sooo different to ours.
We the Baptist's, United, United Baptist, C of E, Catholic's and Anglicans all chummed around together.
Oh and there was one big Ginger (no not Fire Engine blond, he had proper Carrot Orange ginger) oaf, who had been held back for 3 or 4 years; no one of any of the religons hung around with David
The point of all this is even though we didn't discriminate againts other races we certainly did so based on religon.
This I think was a lot to do with our parents, for me it was my mother's influence, which I'm quite happy to say I grew out of rather quickly after leaving home.
Oh, and we didn't have bicycle sheds either
