Unity Among Catholics

Michael Scaperlanda asks: "Can Catholics - whether we voted for Obama or not - come together and agree that President Obama's nomination of Kathleen Sebelius is an extremely poor choice; one that is likely to further divide the nation rather than bring us together?"
I think this question underestimates the diversity of Catholics, assumes that division of the nation on issues is a bad thing (it strikes me that a unified view may be evidence of stagnation) and may wrongly inflate the possibility of national unity (in Obama like fashion - will 2012 bring an Obama-Scaperlanda ticket now that they have struck this important note of agreement on the possibility of national unity?).
I say this without any view of the wisdom of the Sebelius appointment.
