My limited experience for observing violence like this was all white people. They were NUTS. Alcohol was always involved. My own mother was punched in the mouth, knocking out teeth, when she tried to intercede where her brother-in-law was beating her sister (that was before my folks met). That aunt and uncle stayed married til he died, some 55 years after that incident, hitting my aunt regularly. A couple different girlfriends I dated during high school had dads that hit their mothers all the time. My ex-wife’s dad beat his wife AND his daughter.
They’re NUTS I tell you.
I guess it’s the circle in which you live. Never happened, that I know of, in my realm.
My experience was a mix of races but I refer to all of the bad elements as “south of the tracks”...
Many moons ago I poked a feller in a bar after he roughed up a woman. She then broke a beer bottle over my head. Haven’t made that mistake since. I’d hate to be a cop.
