I don't need to go there. The blog you are pimping has a premise that because Palin is a target for abuse from the MSM, she is above legitimate criticism. Erickson's phraseology and comparisons don't really factor into the blog post. It mostly covers the complaints of a few on Palin getting into the race, if at all. I thought the Scientology comparison by Erickson was weak because it doesn't make sense.
He also isn't saying she is above criticism, he never claims that. What he's saying is that Erickson's criticism isn't legitimate, and it seems you agree with that idea.
Peggy Noonan's absurd support for Bambi is a fairly close equivalent to what Erickson's blog post said. It was intellectual dishonesty or garbage, or both.
