What do you mean by "us"?  Who is "us"?  Society?  Government?  A Committee of Smart People?

If we ("us"?), as a society, wake-up one day and decide it's a "right" for white people to own black people as slaves, is black slavery now a right?  I certainly don't think so!

I believe in basic universal rights that have been bestowed upon us by a Creator (yes, a greater intelligence, God, in my case) - and those rights cannot be taken away by a King, a President, Society, or "us."
