Help me, Rhonda

Drake University is bringing some Hoser, eh (and the scientific community is united in that fact) in tonight to lecture on "Reparations to Africa for the Slave Trade".

Rhoda (Drake calls her Rhonda) Howard-Hassman is a Canadian professor and I'm sure will bash America for at one time having slaves.

How come you never hear from these apologists how the majority of slaves were sold into slavery by other Africans (Reparations for Africa?) and that whites too were sold into slavery (Slaves of a different color)?
