All those names

Back in the 40s growing up I listed all those names I heard in my daily life to my significant other yesterday. Why remember? With racism now the rage, why not recall days of NO racism regardless of the names.  Wop, Dago, Kike. Spic, Kraut, Pollack, Mick, Chink, Darkie, Coon, Whitee, Dumkopf (dumb), Swartze Dieffel (black devil) and Holy Roller to just name a few...  Each individual fit into an individual category - so what?  The melting pot constantly stirred. We all got along. Neighborhood by neighborhood. What do you remember?
