A one sided truce? Not likely. It would have to be accompanied by a cessation of the anti-Catholicism on this forum.
And yet Evangelicals are joining Catholics in solidarity in this attack on Obamacare. I doubt Catholics would join Evangelicals in any similar endeavor.
Furthermore, as I have pointed out numerous times, Fundamentalist Protestant FReepers (like Fundamentalist Protestants elsewhere) attack Catholicism from the right. Catholic FReepers (and Catholics elsewhere) choose to respond by attacking Evangelical/Fundamentalist Protestants from the left ("bigots," "fanatics," "small-minded bumpkins not smart enough to join our intellectual urban church," etc.). I wonder if that is how the Pope responded to Martin Luther?
