The local Flea Market here in Pa is in a rural area. People of all types come every weekend, some even come from out of state.
A young black man showed up on Sunday with a Black Lives Matter T-shirt on. He was by himself and kept parading himself up and down the market. Never stopped to look at any of the items for sale.
Everyone just ignored him :)
That’s the best way to treat them - if it is at all possible - just ignore.
Best reaction ever!
