Jim, I don't think you quite understand the discussion.
Some rights are not universal, it is not a simple matter, there are criteria which must be adhered to.
Discrimination on grounds of skin colour is obviously wrong, but as you have admitted there is such a thing as "positive" discrimination.

But who determines what is positive? Is having six wives, marrying your first cousin, marrying someone of the same gender, positive or negative?

These issues are at the very least, debatable
