Well said, Clef.
You're confusing race, ethnicity, and individuality here. Race is in our blood. There's not much we can do to change that and despite genetic disposition to particular diseases and a few nuances in physical variations, I'd say we're all about created equal (especially when in comparison to 'ethnicity'). Ethnicity (cultural upbringing, etc) is when 'un/equality' comes into play. This is a social construct which [purposefully?] undermines the equality of race.
When we move past this and think of murderers, political parties, or whatever, we break social structure(s) down further and for the most part, race/ethnicity become stereotypes in which to judge these things that are--or should be--more accurately described as characterizations of the individual. There are ethnic-based trends/norms, but recognizing these only plays into and reinforces those same socially constructed boundaries, stereotypes, expectations. For countless generations these social constructions have been reinforced and have become the norm, as they are built, quite often, to justify power, rule, subjugation, etc. The powers that be (any of them, worldwide) thrive on this dichotomous thinking. Look at the two party system in the U.S., for example; it simply perpetuates itself because the U.S. population has been indoctrinated to think in black and white, Rep vs. Dem. One or the other. (this is not a political rant, just an example of a divide and conquer mentality/method of subtle social control)
We need more people willing to look past the color of the skin or the genetic make-up of an individual to see through the construct. Continuing to recognize and acknowledge these classifications only continues to handicap us (we become stagnate in the status quo) - not those who are trying to rise above the gate keeping that these structures ultimately create.
We all bleed red and, in general, are all capable of the same awesome things, be they positive or negative.
