The headline should say "AMERICAN Roman Catholic group"
Just "American Catholic" or "US Catholic" - 'Roman' is a word that non-Catholics use to descibe the church. Properly the Catholic church is the "One, Holy, Catholic, and Apostolic Church" not the "Roman Catholic Church". Many Protestants see themselves as catholic. But it's not for non-Catholics to tell the church what to call herself. Some Catholic churches in this country, especially in heavily protestant areas refer to themselves are Roman Catholic. When I see the media refer to the Catholic Church as "Roman Catholic" I assume the article to be bias.
