Well, maybe so. But I think we should still point out when these bloggers go off the rails, and encourage others to think/read for themselves anyway. We just seem to waste so much time and energy tilting at windmills rather than focusing on the very real problems and issues on which we should be concentrating. And the net effect is that the left gets away with a ton of crap because the wacky stuff tossed out there by some bloggers acts like chaff used by an aircraft to throw off a missile.
It's frustrating when you take the time to read the underlying articles and sources, and then get in discussions with people who haven't.
