- Mormons wear funny underwear
- Mormons made official statements that were racist more recently than most other religions made official statements that were racist
- Mitt Romney is a Mormon and he better explain all this
My sense is that Sullivan does not know any Mormons, and thus feels comfortable treating them as an odd group of people who are not part of mainstream society. Which is kind of how some Mormons treat gay people, ironically.
UPDATE: In an article, Sullivan says: "Personally, I have no interest in someone’s private faith in his or her pursuit of public office. Romney, to my mind, should be judged on his public record." It's a fine line here: talking about Romney's Mormonism in terms of its relevance for the public debate versus talking about it as something you have a personal interest in. Sullivan does seem to be walking a fine line.
