It is not the government's job to take my money and give it to those that are in the current spotlight to satisfy "my moral obligation." If I want to give it, I'll do it myself... and far more efficiently, directly, and effectively where most charities and churches are involved.
Also, the Bible is not a binding document on the government of the United States. If you want to back up the "obligation" idea, you'll need to cite the Constitution.
I am not talking about the "binding law" of man. I am talking about a human beings obligation to help out another human being. I am talking about God's law. The AIDS epidemic is not only for charities to tend to b/c it is so monumental in its scope. Millions of people are dying b/c of this. Why would you not feel compassion for these people? The monies that you or I individually or collectively could donate to charities for this problem won't even put a dent in solving this problem. Humanity has an obligation to take care of humanity.
