Bob Dornan is a devout Roman Catholic, who by his actions demonstrates the depth and character of his core beliefs. He decries the problems indicated by the mentioned incidents, but he would never tolerate the way that link was used. It might be relevant in a discussion amongst those of the faith themselves, but not in a discussion covering evolution.
BTW, not all Catholics act alike or think alike. We are not some monolithic group mind marching lock step. The Catholic Church has hosted individuals with as diverse ideaologies as Torquemada and St. Francis, exhibiting a range of piety from the de Medicis to John Paul II. The only difference between Catholics and Protestants with regard to this is that when we have disagreements over something we don't run off and found a new denomination.
