The cause of the African slave trade was black enslaving other blacks, selling some of them to Arabs, who in turn sold some of them to Europeans. Arabs also enslaved whites, but those don’t count I guess. There is still slavery in Africa today, but again, that doesn’t count I guess.
Yep. That's where the word "slave" comes from: the Slavic people that Arabs captured.
Well, according to Putin, the West started the slave trade (of course they did not - but they did end it), identical to this Leftist tripe and historical revisionism, and a significant number of people praised Putin’s speech as spot on where he said Western civilization from its inception has been evil.
