You'll find a more receptive audience for Shea over on Democratic Underground:
Who Is Mark Shea Talking About?

Then may I be so bold as to suggest the outstanding Robert Sungenis? (http://www.catholicintl.com) or perhaps Sonitus Sanctus (http://www.catholicaudio.blogspot.com) or the Institute of Catholic Culture (http://www.instituteofcatholicculture.org). Heck, there are many good sources for information, folks. If I can find them, I know you can find them.
If you read his blogs you know he is firmly pro-life and supports traditional marriage.
He is against torture and was against the war in Iraq. A lot of conservatives agree with him. So what?
Regardless, all other issues of politics and economics are prudential questions. I don’t agree with him on all areas of politics but his books on theology are based on excellent scholarship and logic.
If you want to read from a excellent book about Mary from a very conservative Republican (and a former Protestant minister), read Scott Hahn’s book “Hail Holy Queen”.
