Actually, it all started with slavery. They were forced here by brutal slave traders. And then a couple hundred years of horrific treatment followed. This stuff has everything to do with Slavery.
Their own tribal chiefs sold them into slavery.
The problem with you wanting me as a white person to apologize for slavery is that not one member of my family ever owned slaves. I have nothing to apologize for nor is such an apology warranted. If you want an apology get all those that actually owned slaves to apologize to those that were slaves.
