-——If serving Ritz crackers and cheese at a party is an example of racism———
I think the problem is the cheese. The man and his race in general, are lactose intolerant. He assumes everyone, every hostess, should know many if not all of the black guests suffer from lactose intolerance and can’t eat cheese.
Not an expert here, but I’m pretty sure the ‘lactose intolerant’ CAN eat cheese. Intolerant of cheese would be some kind of allergy that I don’t believe is widespread.
So change it to crackers or cheese...problem solved.
