wearing denim cargo shorts, would you not tell him he looked like a dipshit? And would saying that neccessarily mean you hated him or that you were some type of asshole? Not really. And its the same principle here.
If your dipshit friend then stormed out, went home, and later sent you 5 emails crying about "how crappy your friendship had become" and how "beauty is in the eye of the beholder", he'd be acting like spdracr is right now.
