Agreed. I was twenty and went to a Halloween party with black face. Black arms and hands, too. I didn’t think anything of it - other than it was funny. I still don’t think anything of it, regardless of the hoopla.
We had, in 1966, a black guy come to a Halloween party dressed in Klan robes.
Another man (white) came as a Buddhist complete with a gas can(empty) as that was when they were setting themselves on fire in SE Asia. No one got offended.
