Are blowjobs really that offensive, to make you comment about it? I mean, on the scale of offensive horrors, blowjobs can't be too far up there, can they? I'm honestly asking because someone else made the same remark in the comments on the post, and I simply cannot comprehend how this is a big deal; am I too open-minded or young to see how the imagery was offensive? My wife's very Mormon family has joked with me about far worse subjects, so I don't really have any perspective here. I know people get offended, but I've never really dug into why.
