Abrenuntias omnium?

Here is how Barack Obama should handle the ritual flagellation imposed by America for the crime of being an uppity Nigra:

Dumbass Racists: Abrenuntias pastoris tuis?
Obama: What?
D.R.: Abrenuntias uxoris tuis?
O: Have you lost your mind?
D.R.: Abrenuntias omnium nigrorum?
O: I renounce YOU and your racist filth, that's what!
