The Must-Have Insult

Which is "You're a racist!  Things are getting kind of bad, so please be aware...

 The other day I overheard this exchange.  Two women of a certain age were discussing summer foods from their perch on a waiting-for-the-bus bench.

Purple dress: " Oh, I do like a nice tray of iced  crudites in the summer but they can just leave off the radishes and add more carrots instead!  I don't like radishes!" and gave a delicate shudder.

Woman in yoga pants and billowy top:  "Ohhh, you're a racist!"  and so saying, slid a little further away from Purple dress.

Both then ignored each other in favor of looking up the street for the bus.
