As usual you have it backwards, O Contrarian. The moral-liberal LP Brownshirts want to prohibit prohibitions. They want to rob people of their right to determine what kind of a society they are to live in.
As opposed to the moral-authoritarians who want to rob the "people" of the opportunity to develop their own moral identity. Rather have it imposed from the top down by a learned council of moral elders, just in case a few happen to get it wrong; that's so much more "god-like," if only in form.
Precisely what the FOUNDERS were after. Maximizing freedom.
