I’d never heard of Prof. Bell, so I looked him up.
- 1957 - got his law degree (that in itself was amazing)
- 1957 - William Rogers, Assoc Att General for the US, recommended him for Justice Dept, where he was hired and was the first black professional (William Rogers was the Attorney General under Eisenhower and Sec of State under Nixon - obviously a well known radical himself)
- The Justice Dept asked him to resign from either the Justice Dept, or the NAACP. He resigned from the Justice Dept
- At the NAACP, he worked with Thurgood Marshall, later a Supreme court justice
- He sprearheaded the fight of James Meredith to enter the U of Mississippi as the first black student
- He taught at Harvard, Stanford and NYU (all top 5 law schools) and became Dean of the Oregon School of Law.

I don’t know whether he’s radical or not. But after reading his bio, I think he had a right to be any damn thing he wanted.
