Hurrah. I couldn't ask for anything more. This is proof of why it's better to debate on FR than to post comments on blogs.
I'll be anxious to find out the results of your research. Sending a question to the EWTN Q&A would be one way to test the waters, but we already know the answer there. I'm sure you can come up with some other sources where you can test the reactions of "leading NFP proponents."
Some might simply offer it as proof that I'm more of a "closet radtrad" than a Neo ;-)
