Snark aside, I think Yglesias hits on an often overlooked point:
On this view, a person who led an entirely exemplary life in terms of his impact on the world (would an example help? Gandhi, maybe?) but who didn't accept Jesus as his personal savior would be subjected to a life of eternal torment after his death and we're supposed to understand that as a right and just outcome. That, I think, is seriously messed up.
Yes. It's one thing to believe to the core of your being that in the Grand Plan established by God that accepting Jesus is a necessary step to avoid eternal torment, but that belief walks hand in hand with the one which says that God's Grand Plan is a Just and Wonderful Plan.
And, no, I'm not going to STFU and stop telling people that if they think that then I think their moral universe is pretty messed up.
