There are actually some pretty damn racist tweets in there. One tweet imagines Clarence Thomas's reaction to Scalia's death as being similar to the scene from
Django Unchained where the house slave Stephen (Samuel L. Jackson) mourns the death of his master Calvin Candie (Leonard DiCaprio).
For the record, Clarence Thomas has been quite independent of Scalia. He has been far more intellectually consistent and honest. Scalia was more entertaining with his ascerbic wit, but Thomas is, in my opinion, the best justice by far. I doubt that virtually any of Thomas's detractors have even read any of his opinions, let alone understood them.
