Delusional John Hinderaker thinks only left engages in "personal intimidation"
A disturbing new element has crept into our political life: organized efforts to intimidate private citizens who choose to support certain political causes or otherwise participate in civic affairs... [examples of leftists swarming houses of their opponents and much more deleted] ...Conservatives are decent people and don't engage in such repugnant tactics.
The last sentence of the excerpt  would only make sense if Hinderaker had never heard of the tea parties. Since he's clearly heard of them, is he either delusional, or is he trying to mislead?
One of the reasons why I oppose the teapartiers is because they act just as badly as vile leftists. Certainly, no teapartiers have as far as I know swarmed the houses of their opponents. However, they have thrown dollar bills at a Parkinson's sufferer (see the last link). And, about the only arguments they can ever present are vile ad hominens, as I well know. For just one example, see this. For more, see some of the posts at the tea parties link above, or Glenn Reynolds trying and failing to whitewash how the teapartiers have acted, or some other posts on the Glenn Reynolds page. For even more, see some of the replies I've received from teapartiers are various sites, such as Ann Althouse (as "LonewackoDotCom").
I even coined a term for how the teapartiers make an argument: the Jump, Smear, and Lie Technique. And, because of that technique, I have to point out that this post is not in any way supportive of leftists swarming the houses of their opponents. (And, because I know full well how teapartiers operate, I know they won't bother clicking those links.)
The point of this post isn't to support Leftists Behaving Badly, it's to point out that self-styled conservatives are now acting almost as bad. And, all of that was done with the silent (or not so silent) assent of their leaders.
 In the full post, Hinderaker mentions a supposed plan by Robert Greenwald of Brave New Films to film the houses of the Koch family. I oppose both parties: Greenwald for supporting illegal immigration, and the Kochs for funding loose borders groups. Hinderaker can only rise to opposing one of those parties. Hinderaker also mentions Katrina vanden Heuvel, just not in the way that I do (see the link).
