The only way an idea like this would work is if it has strict, set-in-stone rules about what counts as what. For example, if a senator says "the white devil is responsible for all the world's evils", that is a demonstrable attempt at oppression. If some crackhead from Baltimore says it, it's just trash being trash. Not all evil is created equal.
It would almost be like a Wikipedia for power mongers and rich sociopaths. Anyone can contribute, but there are still rules to follow.
