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?
Your friends are easily manipulated idiots who are eager to virtue signal and fit in with the other sheep. Mine are pussy pandering simps. Anyway, I guarantee they don't know history or the context of any important events. Dinesh D'Souza is someone who has done a lot of work in exposing Progressive lies and their rewrites of history. He has a youtube channel and made a few movies on the subject and is still very active today. I'd recommend sharing his content and even checking it out yourself if you want to arm yourself with knowledge against progressive indoctrination.
