Contra Nicholas Kristof [Email him] there are lots of viral videos of what our "Jim Crow" de facto segregated school system. They show black kids beating other black kids, beating their teachers, and beating white kids.  This was the subject of the book White Girl Bleed a Lot by Colin Flaherty, and many articles here and in American Renaissance.

Years ago, before viral videos, Steve Sailer proposed a way to prevent white kids from growing up with racial prejudice.

His article was called Preventing Kid Prejudice: The Sailer (One Point) Plan

His one point:

1. Don't let your children get beaten up by underclass minorities.

The video shows him sitting alone, facing front, when the attack begins from the rear—and continues from the side and the front of the school bus. “I didn’t do nothing,” he protests

The videos below, undeleted so far, show beatings at black schools, one of them named after Frederick Douglass. It's why white parents don't send their kids to these schools if they can help it.
