I hardly think that the IRS has a special branch the separates the money paid by white taxpayers from those paid by black taxpayers - of which there are many. Your comments sound racist to me.
You don't need to segregate the money. Just look at what black Americans - as a group - pay in taxes. Then look at what black Americans - as a group - cost in terms of social programs and law enforcement. You'll see that it is a net negative. In other words, if all the blacks in America moved back to Africa, the Treasury would show a net gain. That's not racist. That's just fact.
