Many progressives here advocate blocking, or lacking that, ignoring disruptive posters. While I understand that approach, I am more inclined to engage from time to time traditionalist who exhibit serious knowledge of the magisterium beyond catechism. I figure that it is important for us to never forget that the Holy People of God includes huge numbers of traditionals who are entitled to our respect as fellow Christians, as alteri Christi. 

But Marty E, it seems to me, is something different. He has serious knowledge, but seems to be lacking a willingness to actually engage in intellectual discussion. I find that disconcerting.
