The point
I don't think the point of the article was to say that people who advocate gun prohibition are doing it out of conscious racism, but I think there certainly is some tiny unconscious racist element to it in some cases. The point was to explain how gun ownship control has its roots in racism and the desire to maintain control and limit the rights of the powerless. Now the argument is that we are trying to keep guns out of the hands of criminals. In fact, it is only out of the hands of the law abiding we can ever hope to keep them. That seems pretty ass backward to me.
My opinion is this and if you feel you must detest me for it, fine. I believe that gun ownership prohibition, particularly in those environments where there is the most restriction on ownership - typically urban areas - specifically targets those people who have the most genuine need for self defense and specifically prevents those same people from having any legal means of effective self protection. Clearly, the criminals who prey on those people are not in any way constrained by gun control laws from acquiring firearms and yet some people would argue for the morality of disarming those people who are their victims.
It is also true that for the people in those areas the notion of police protection is a laughable notion (which it pretty much is in any case - "call 911!!!"- unless, of course you live in a gated community with million dollar houses.) And I would argue that even if the intention of gun control is not racist, its net effect in many cases is.
