Do you have any evidence whatsoever that the people who drink and drive are harming anyone in any fashion whatsoever (aside from making other drivers nervous, of course)?
I'm sorry, but that is a really stupid analogy.
17,000 people every year are killed by drunk drivers.
Makes any comparison with owning guns irrelevent, doesn't it, since simply owning guns DOESN'T kill anyone?
I'm surprised you didn't weigh in with your opinion of the original statement which limits the law to harmful activities. Why didn't you? Which society or government uses (or has ever used) that standard? Wasn't that a stupid statement?
But I apply that exact same standard to DWI and that gets your attention. Interesting.
