Has the pope spoken authoritatively on the Standing Rock Sioux and Cheyenne River tribes?

How am I a racist for saying that Sharpton is a shakedown artist?  You can't count the number of black people who have classified Sharpton as a shakedown artist.   And declaring him a shakedown artist isn't a racist act, either.  

So here's the todo list:

1. Show formal teaching from Pope Francis on this topic.
2. Substantiate that black people who classify Sharpton as a shakedown artist, aren't racist when they do, but I am.
