There is really an extensive amount of literature and research behind this, and your ignorance* of it does not mean that "racial activists" "just assumed" it to be unwarranted. A good example is the difference in mandatory punishment for crack (a stereotypically "black" drug) vs. cocaine (a stereotypically "white" drug). Despite the fact that whites use schedule II drugs at a rate at least proportional to blacks, blacks end up in prison for longer periods of time and in much higher numbers.
Can you tell me where the impetus for legislation as pointed as this comes from? Does it come from cries from within communities to put a stop to it?...Maybe?
I'm not dismissing the white privilege discussion here...but I think this specific example did not come to be because white people thought crack was a black mans drug, or even worse than coke...I believe the communities where crack was prevalent, and its apparent impact drove urgency and thus the disparate punishment...
Which is not to say that drug use is ok, or that because drug penalties are unevenly applied, all blacks are doomed. But it does say something about the way our society is structured, which leads to your next point. Single parent households are a problem. But is that really surprising when 5% of your adult male population is incarcerated? There's a pretty serious feedback loop in effect, which makes it difficult to sort out the self inflicted damage with the damage inflicted by the underlying structure of the system.
I think liberals, in general, focus too much on the systemic harm while conservatives focus on the self-inflicted side. The reality is that if America is going to reach its true potential as a nation, both sides of the balance need correcting.
As a white male, I view it as my responsibility to focus on the systemic side of the equation. There are plenty of black advocates out there who are fighting to focus on education, family values, staying out of jail, etc... They don't need my voice telling them how to fix their problems. And I think that's what people like NoJusticeNoPeace found so disturbing about a lot of the comments being made by (white, males) on IE. There is something stunningly condescending about telling someone that their race should just go fix itself. On the other hand, systemic change is something we all have a stake in. We might not all agree on the best rules out there, but I think we can agree that our system should treat everybody equally, regardless of skin color. To the extent that it doesn't, that is a problem for all of us: white, black, yellow, brown, and everything in between.
*just to be clear, I am not calling you ignorant. I think you're a wonderful poster who adds a lot of value to IE and I'm mildly upset that you stopped doing your post-game recaps over the last few games of the season. I use the word "ignorance" here in a very narrow context- based on your comments, it appears to me that you have not read any of the academic studies on systemic racial inequality.
