Listen, I am not going to try and change your mind. If you want to believe that the problem is a person’s skin color, and not the content of their character, or the environment/ideology that shapes that character, you go right ahead.
I am telling you that if you do go down that path, then you are missing the big picture, and there is little hope that you will be able to add anything substantive towards finding a lasting solution.
I can't fully explain why violent crime is mostly confined to one group, but you cannot deny the fact that it is.
Looking at various breeds of dogs, one notices that certain breeds have genetic predispositions to certain behaviors. The average golden retriever does not behave the same as the average pit bull. This does not mean that there are not aggressive retrievers or docile affectionate pit bulls, but average behavior is something people take into consideration.
The politically-correct meme is that the only difference between races is outward appearance, and there is no correlation with average testosterone levels or other internal characteristics which might affect outward behavior.
