I'm not so sure a cartoon of Joe Ratzinger waving a gavel is "hate" speech, or even "anti"-Catholic. Not knowing what issue the cartoon was aimed at (I'd like to see it, if you don't mind posting it) but I'm not quite ready to take someone's word without know.
I already know MoveOn.org is scum, but before forwarding around a bunch of someone else's talking points, I'd like to see the examples they refer to.
