I'm a lifelong Catholic, and I've worked in the Catholic Church all my life - so I know the situation in the American Catholic Church quite well. Despite the official stand against homosexual sex, most priests and nuns I know are very sympathetic to the concerns of homosexuals. And it seems to me that most Catholic lay people and bishops have attitudes that are far more rigidly opposed to homosexuals. Many Catholic priests and nuns aren't particularly pleased about the idea of anti-homosexual Anglicans joining the Catholics.
It's a dilemma that's not as easily resolved as one might think.
