I think the difference is that I don't give a rat's ass [no pun intended] what Andrew Sullivan does, or thinks, or feels, or cares about, or pre-occupies himself with, or what legal contracts Andrew Sullivan does or does not want to enter into, i.e: I'm not trying to shove an agenda down Andrew Sullivan's throat [again, no pun intended].
If I change my position on Bush because of my heterosexuality, than yes my arguments are suspect. Sullivan supported Bush up until last week when Bush announced his support of a constitutional amendment. At that time, Sullivan went nuclear against Bush. Sullivan's views are clouded by this, so I don't put much weight into Sullivan's disingenuous rant.
