About 30 years ago (when my balls were bigger and my brain smaller) I was driving a taxi and, one night at about 1:00 am in a donut store parking lot I came across a guy beating the shit out of his girlfriend. I got out of my cab to try to stop it. As soon as I said something the guy stopped hitting the woman. So far so good, right? Then the woman starts screaming at me "You white honky ass motherfucker! Mind your own fucking business asshole!" So I just said to the guy, "Have at it," got back into the cab and drove away.
