It's plus ca change in the blogosphere. Andrew Sullivan and Leon Wieseltier are feuding. The spark for the latest round was, apparently, a WH Auden quote from 1944. It's a remark about the difficulty of explaining the concept of the Holy Trinity to readers of the New Republic. If you're snowed in, you've time to read the whole dispute. But of course the Irish perspective (which given past practice Sullivan may invoke at some point) is to ask -- the Trinity: what's so difficult about understanding it?*
UPDATE: As predicted here, Sully's response twice refers to his Irishness (and with a Morrissey tone), although not in connection with the ability to understand the Trinity.
And yes, we know the shamrock thing is probably a myth. Image from Wikipedia
