Large Catholic churches are pro-abortion? That is news to this Catholic.
Most clergy I've met in the big Chicago Archdiocese, especially those from Mundelein Seminary, and especially the non-Hispanic clergy, condemn abortion about the same way you'd condemn a person who lied about the Easter Bunny.
This past Sunday at my church, the pastor gave the homily rather than one of the ex-nuns. In his homily and in blessing the sacraments and in the final prayer he emphasized "honoring the family in whatever form it happens to take without condemnation". The homily was all about diversity of forms of the family. Read into it what you will.
This November, the US Bishops are pushing collections for the Campaign for Human Development. The CHD funds both pro-abortion activists and political activists ... more Dennis Kucinich and ex-nun Marcy Kaptur type than John Kerry type Catholic Democrats.
