I'm saying you're sugarcoating it because you imply that 'well, the african slave trade wasn't all that bad...' They had good systems in place, and it was done honourably!
Well; it wasn't. All those slaves that went to the Americas were sold by native groups. Sure; having defeated warriors as slaves for a few years was normal all across the world. Selling and buying, however, wasn't.
You seem to imply that the Europeans enslaved them. Not true. They BOUGHT them. Those people were already enslaved. And this practice of slavery wasn't by far as honourable as you made it out to be.
I could say 'Well; the vikings were really honourable because of their customs!' I'd be completely ignoring the fact that my ancestors made clothes out of Christian clergy. And books. And cups.
Edit: For clarity. To enslave someone: To make them a slave.
To be enslaved: To be a slave.
You can be enslaved in the service of someone who didn't enslave you. Thank heavens the whole slave business is illegal in most parts, now, but slavery is still a hell of a large problem world wide.
