Banning tipping in bars? I'll have to go watch that one when I get home.
Frankly, though, this is not the sort of person that I worry about. OK, I guess we should all worry about someone who thinks it's OK to just mow somebody down with their car. But he's not the sort of guy I worry about on the 2A front. It's clear that he's not quite right, which makes him easy to discount. The ones that worry me are the rational-sounding ones.
