I don't think I'm being an insufferable ass. But I'm guessing anyone presenting an opposing viewpoint would come off that way to you.

I'll admit I find it pretty offensive that this hypothetical guy is getting lambasted for not being physically attracted to someone who has put on, and presumably kept for a while, a lot of weight. As if physical attraction is something you can consciously control. It's also tough to see consent being treated so lightly in this circumstance. As if this guy should just put aside his own feelings and pop a viagra so his wife's feelings don't get hurt. Anything resembling that mindset in a reversed gender scenario would get called out for the garbage it is.
