Katz -
So you are comparing slaves being herded on to slave ships with ordinary passenger ships.....?
I am speechless.
I am comparing conditions. Not the circumstances under which they got on the ship. Slaves got on the ship because they were captured by black people and sold into slavery by black people. The descendants of those slaves have much better living conditions today than the descendants of Africans who were never captured by their black countrymen, nor sold by their black countrymen.
