It's funny, but when I went to HS back in the late 70's and early 80's, there were a handful of black kids (I'm going to guess 50 out of 1,200) and as far as I'm aware, no-one ever gave them a hard time. In fact, quite the opposite. They were all considered to be very cool and people gravitated towards them and sought out their friendship.
One black student even became the president of the student council in my Grade 12 year and several were "mentors" to the Grade Nines.
Fast forward to today and my niece (who lives in Burlington) tells me horror stories when it comes to racism. Shit we just never dreamed of, or would have actively shut down in its tracks. Maybe it was a simpler time and we were all born in the 60's and that 60's thing was still happening, even in the late 70's and early 80's. (Or maybe I just didn't see it, who knows.)
