I searched as best I could outside of sports for videos of whites beating blacks but couldnt find any,,,
maybe some of you will have better luck than me,,
There are a few. I can think of two off hand. One was some sort of pimp causing trouble, and a martial arts instructor knocked him out. The girls came and carried the black man away.
The other was some kid, who wanted to fight, and he picked a white kid to fight, and the white kid knocked him out.
What you don't generally see, is that happening randomly. White people generally do not randomly attack others.
There is no "knock out" game for white people generally. They usually fight, when you give them no choice.
