You are basically correct in attitude and desire.
There is only one problem. Much like the “Moslem” problem. It is the culture.
You are indeed right that there are blacks, e.g., who do not like what is happening in their cities, etc., but they are far and few.
When blacks vote 90% (low estimate!) lockstep the same way all the time, the picture is clear.
Other minorities may vote majority Dem, but they are not as totally predictable.
It’s a pretty good guess black attitudes and actions on just about anything are going to be 90%+ the same predictability.
Your entire comment is a must read and states the facts in an honest manner not colored by emotion or rancor. The numbers don't lie. The reality is that for every Clarence Thomas, there are around 90 Trayvon Martins. Likewise, for every Allen West (himself a wee bit soft on the matter of Travon), there are some 90 Michael Browns.
It's not the color, it's the culture. And I fear that the culture is beyond the point of being redeemed. And frankly, I place large part of the blame on a Republican, none other than Chief Justice Earl Warren. He probably meant well but his rulings set the stage for the mess we see all too clearly today.
