Why do blacks hate slavery?

This may sound like a stupid question.

Yet I'm wondering why do they hate slavery,
after all if it weren't for slavery in the U.S.A,no blacks or hardly any would be in my country today...

"educated" aka brainwashed. Whites are told that everything white is bad, and everything non-white is good.
And the way you speak show you are either a filthy jew spreading brainwashing, or a diseased treacherous scumbag.

The reality is race and genetics determines who you are.
