What does that have to do with what the criminals are doing today? At least Madison and Jefferson didn't break the law or trample the Constitutions Slavery was legal; perhaps not morally right, but still legal.
So, what are you suggesting, garysher? that because Madison and Jefferson held slaves we reject their wisdom?
Pretty good argument, garysher! I said the politicians in office now are selling us down the river, destroying the constitution, ripping our freedoms to shreds and all you have to say, "Yeah, but Madison and Jefferson held slaves".
How many slaves did they have, do you know? And how well (or bad) did they treat them?
I could present a lame argument, too, like, "Yeah, but the African Negroes sold them to the white traders."
See how dumb that sounds?
