And I agree with interpoltomo that the War On Drugs is ideologically different from social conservativism.
In terms of the political currents we're discussing, a dubious distinction.

And a man who believed that hardcore porn certainly should be illegal, among much else. It's all a mutually compatible anti-Warren oort cloud.
You're aware of the racial issues in drugs policy and sentencing, right?
