Good point, Kevin57.  There was a time when a Catholic organization could be at risk of losing any official Catholic Church support and affiliation if it were to partner with another organization that might have a website link to a link to a link to a pro-choice effort.  Personally. it makes all the sense in the world to partner with organizations on common causes even if we disagree on others, but the anti-abortion crowd has never been fond of this approach... until Koch money came to town.
