This is literally what he sent me:
You're offspring will reap the demise off your ignorance, be it slavery or another form of retribution. You're unwillingness to acknowledge injustice will bring the wrath of vengeful and irrational beings, seeking reparations in blood. I sought to enlighten you to a reality you were not privy to through the stories of people who lived those hardships. Those "criminals", as you call them, will come to eternally rob you and your next of kin of light... I wish the best for you.
Really fucked up stuff, this was a good friend of mine. What happened to people?
As a black person, I really can't stand white BLMers especially. It's like they want to be oppressed or something as a fad. My advice is to tell your friend that although you disagree on the topic your friendship with them is important.
It's not important anymore. We're done.
They said some pretty harsh shit, they really drank the kool-aid didn't they? Hopefully one day they'll wake up from the MSM trance. Just like a liberal they brought up your kids too, surprised you didn't kick his ass on the principle of the matter.
