...when black will not be asked to get in back...

I think "when black gets off of crack" has a better ring to it, and it's no more repugnant than the rest of his prayer.

[Revolting cat!]

Here is a start. Feel free to make improvements:

“We ask you to help us work for that day when black gets off the crack, when brown don't paint the town, when yellow ain't the smartest fellow, when the red gives a better casino spread; and when white don't vote for a piece of scheiss!”
