If liberals weren't so historically, damnably IGNORANT, they would realize that EVERY group of people on this planet has been abused and brutalized at one point or another in history. ALL races have a bloody history, not simply the whites that liberals love to blame for everything. Hell, the biggest mass-murderer in recorded human history was NOT WHITE. He was an Asian named Mao Zedong. Human history is universally barbaric, no one race owns the ultimate monopoly on human rights atrocities. Which makes liberal "white guilt" nothing but arrogant, preening, virtue-signaling posturing from atop a golden pedestal.
What is not acceptable today was acceptable years ago. Most people don't know it, but even God approved of slavery.
When a man brought shame or damage to a person or family, they didn't have lawyers or courts around. Nobody had any money to sue anyhow. So people enslaved each other to repay a debt. If a father caught his daughter with an unmarried man, that man brought shame to the family and he was enslaved for a period of time deemed by the father. It's just the way people did things long ago and it went on all over the world.
Of course in a more civilized time, we now look at slavery differently. It was barbaric and oppressive. It was a wrong thing to do by today's standards. And who knows? Perhaps in fifty or a hundred years from now, people will consider us barbaric for owning pets, having boxing matches, or mixed martial arts. But today, these things are acceptable in our societies.
