I strongly recommend AGAINST anyone adding bile to their letters. I assume that CCF believes D&D is a work "of the flesh" and showing rage, anger, upset will only serve to confirm them in that belief further.
RMS -- it may be if they are Jack Chick - type believers that they will not consider Catholics Christians either. Yeah, I know. But we can discuss that offline.
Hm. Point...in light of this, might I reccommend changing "Catholic" to "Christian"? No meaning is lost, and it sounds less...denominational? Again, trying to approach a common understanding, as it were. It'll work wonders.
