Okay, so your big beef with Cam is that he doesn't distinguish b/t morality and preference. Is that right? He is well within his rights to say that he finds anal sex disgusting. Or is expressing an opinion wrong too?
I correct that you don't have a problem with assisted suicide? That its actually immoral to prevent it? Just checking. I'll go out on a limb early and say I agree with this POV.
The suffering argument is only one way to approach questions of morality, tho. There are those who would say that individual suffering doesn't matter a whit.
Second thoughts can generally be amended with judicious action; injudicious actions can seldom be recovered with second thoughts.
