1. When Things Like This happen, what we should all do is talk a lot more about Jesus of Nazareth.
2. If someone quotes him, however, what we should do is ridicule the quotation.
Yeah. I got the Rush thing from an Amanda Marcotte tweet; she read it as "Criticizing a conservative is the same thing as raping someone in Limbaugh's world." I suppose so, but what I read is Rush hearing "turn the other cheek" and thinking of it as some sort of weird, alien phrase to be mocked. That is, he didn't explain that this was a poor time to be following the biblical advice, or that it didn't apply here, or whatever; he went after the idea of "turn the other cheek" itself.
Me? I don't like to mock serious thinkers, so I'll pass on Rush's suggestion. As for Erickson...I guess I'll meet him halfway. As a Red Sea Pedestrian myself, I won't quite go for what he wants, respectful as I'm sure he means to be to Gabrielle Giffords by implying she (and I, and the rest of us heathens) is bound for eternal damnation. But I'm due to resume rewatching Buffy from the start of Season 4 soon -- it's light on Jesus, but long on heaven, hell, and of course lots of very real demons, and Erickson wants us to focus on that sort of thing. Hope he doesn't mind the improvisation.
