Well in regards to the Mission Accomplished dealy, it was relevant to the discussion, entirely.
Seeing as the topic being discussed was disrespecting servicemen, I'd say it's actually as close to a perfect comparison as I've ever seen really. The question he is trying to make you ask is "Did you think it was disrespectful of Bush (back when he was on office) "saying" mission accomplished?"
But excuse me, my memory falters.. Did he actually verbally say it, or was it just the flag in the background?
"George Bush says he speaks to god every day, and christians love him for it. If George Bush said he spoke to god through his hair dryer, they would think he was mad. I fail to see how the addition of a hair dryer makes it any more absurd."
