buys, what do you say to the idea that if African slave trader merchants refused to sell slaves then no one could buy them?

I guess you could say that then there would more kidnapping then there already was...

(I should say this is all to get dialouge, I'm not actually saying this is how I think, but what of the idea of "two to tango", in that it isn't wholly the Europeans fault, that they forced the Africans to sell them slaves just based on the fact that they were in fact buying)
