Whether we're talking about the right or the left in the Church, the parable that comes to mind is the one about the wheat and tare.  It seems that all of our organizations are composed of both.  Discerning Catholics should be able to sort through and see what's good, even as we deal with our own personal wheat and tare conflict.  There is sort of a dialectic going on here—good vs. evil, light vs. dark.  We know how it will end (it's actually ended already) but we have to live it out.

So go at it NC Reporter, NC Register, America, EWTN, progressive-but-faithful Catholics, Opus Dei-ites, Dubia pushers, field hospital denizens.  You are all in this big catholic tent of ours.  And the truth will out.
