Your distinctions seem a bit arbitrary, John. I've met vegetarians who would happily legislate against eating pork, for example, on the basis of no "holiness" whatsoever. Perhaps you mean that laws shouldn't be based solely on a religious prohibition? Still arbitrary, though; I see no reason why atheist prudes should be allowed to outlaw marijuana or prostitution, but religious prudes shouldn't.

The motives don't matter; the restrictive laws do.
