No it's not.
Im not quite sure America has paid for the mistake of slavery, but even if it has paid for that mistake, it does not minimize that mistake or absolve America of slavery and placing African Americans in scientific experiments.
You're a liberal. You always have been.
Let me get this straight.
It is your view that only a liberal would acknowledge that it was a mistake for Americans to hold African Americans in slavery and place them in scientific experiments?
And since it is apparent that you believe that only a liberal could recognize the evils of slavery, could you please point me to a Conservative leader who like you would not see American slavery as evil?
