Ah yes, of course. So, we just ignore that current injustices that are happening day-to-day and "move on"? We allow racism and discrimination to remain untouched as we "move forward"? Yes, how foolish of me. Clearly this will fix all our problems and get rid of that hate you were talking about.
And Nimin, do you really think it works that way? That you can just go, "Aww gee shucks, even though the system is designed to step on me and keep me down, all I have to do is just stop crying and everything will be alright!" Holy fuck, talk about naive. This isn't about individual circumstances, though those definitely have an effect that shouldn't be ignored, it's about how the law, and the economy, and rules, and perceptions are set against minorities, or set in favor of the majority, rather than being equal.
Also, "centuries ago"? You do know that Jim Crow and the Civil Rights era were less than a hundred years ago, right? You do understand that the position your grandparents are in affects your parents, and that affects you, RIGHT?
I'll give you an example. My grandparents are farmers, and have been their whole lives. If they had been black, chances are they would've struggled to purchase the land that they worked for decades, because the system has HISTORICALLY been heavily biased or outright hostile against black people. My entire family might not have been born, or would've been born in completely different circumstances, thus leading to ME not being born. If you can't understand how this shit can affect people on a generational scale, then I don't know what to tell you.
