There is a reason you won't see the tea party hanging around outside of politicians' homes. That's because it is incredibly inappropriate. It's behavior which is designed to intimidate in the worst kind of way. Yet in Wisconsin, and elsewhere throughout the country, liberals find this tactic to be acceptable if not preferable.
This kind of intimidation has no place in our society. "We know where you live" is the inherent message here and it simply doesn't belong. Then again these types of completely uncalled for tactics are par for the course on the left aren't they?
