I remember being a 10 year old kid in 1961 on Staten Island out shopping with a baby-sitter (who eventually became a nun). There were a bunch of people who were passing out fliers. I only caught a brief glimpse of it as a guy handed a flier to her. I saw a caricature of black person and the "N" word(you can bet there were/are as many, if not more, racists up north).
When I reached for the flier, she crumpled it up and told me not to pay attention to "that crap" (which is as close to a swear word as I ever heard come out of her mouth). She sat me down on a bench and told me that was absolutely wrong to judge others by the color of their skin. She told me that people who make such judgments are sick and that I should pray for them. That has stayed with me to this day, even though I don't usually pray for them.
