The Voice - Make all the black contestants face each other in the knock out rounds/battle rounds so 1 of them is guarenteed to go home unless a coach saves them.
Survivor - Vote off the female asap, vote off the black male right before the merge or right at the merge cause he's a threat!111
Big Brother - Wait a couple of weeks so you don't look rasis, then by week 3-4 put them on the block so they have a chance to fight for veto, wait for them to lose (since black people don't win vetos), and evict them pre-jury.
The Challenge - Vote them into elimination cause you're not as close to them as you are to everyone else. (lol looking at free agents voting chart).
