The first half of the article paints the FBIs work against the civil rights movement as an anti-communist movement so fervent that it caught up the civil rights movement along with it.

I'm sad to see this accepted so uncritically, especially as the rest of the article belies it. The truth is that american leadership opposed the civil rights movement because it challenged their power and wealth. Communism is just the boogeyman used to justify surveillance and sabotage.
