I don’t know what the current disagreement is, especially given that my comment centrally agreed with both you and the other commenter. I just pointed out that you were talking past each other in an unproductive manner.

You don’t think there’s a distinction between alcohol’s penetration into all American communities and the targeted attacks against the black community by planted narcotics?

As you claim, it is just a difference of scope. The Quote which constitutes most of your comment, at least without further context, doesn’t seem to be stressing the discriminatory drug sales but rather the pernicious nature of drug sales.
