Your understanding is too simplistic. Genetics is more complicated than that. Observed differences are studied for environmental influences and hereditary influences through the social sciences and attempts are made to understand the effects of each. Social science can never be an exact science.
To make a declaration that blacks are more predisposed for criminal behavior than whites (or any other race) is a statement that insists of a basis in scientific territory.
If your entire reason for believing such an adsurd idea is only based on assumptions and conclusions found in the liberal arts, then what does that really say about the foundation of your belief?
The issue isn't that my understanding is too simplistic. The issue is that you have no supporting data to validate the claim other than bias.
While you may even have a handful of biased supporting authors, the vast majority of study in the field contradicts those handful that you would clamor too. And you can insist that it's not an emotional attachment for you at all, yet clinging to an idea that has been handily refuted for a long time would indicate otherwise.
You have made the argument that blacks are more predisposed to crime, genetically. I'm only asking you to support that in any form other than pseduo-scientific fashion, followed then by copping out and saying we are each entitled to our own opinion...
If blacks are more predisposed to crime genetically, then by definition there has to be some basis in the genetic study of that population. If there is no genetic science supporting this claim, then it needs to be recanted.
As you have yet to supply this forum with any peer-reviewed articles supporting the idea, are we to assume that the supporting data simply doesn't exist, leaving the foundation for such a claim absolutely baseless?
