Wow...Ignorance is one thing, and can be excused...as all it means is one who has not been educated/made aware of the facts.  The problem is with willful ignorance...which is a refusal to educate yourself.  It would appear that you, sir, are the racist as your statements indicate a racist mentality with respect to another race.  You apparently assume only blacks were slaves!  If you did your homework, you'd find out that slavery has existed in every culture at one time or another, including black cultures.  White people didn't go into the interior of Africa and capture slaves, they bought them at the coast...sold by other blacks.  You obviously have been indoctrinated and have no desire to educate yourself, enjoy your angry life!
