Oh Jansenist. They're a special kind of crazy. Most of them deny literally everything past the Council of Trent, and think that Church, was once the Church, but stopped being the Church, and its legitimacy has transferred over to their "Old Catholic" church....because that makes sense. I know that two of them that were basically just libertarian shills, who I got the idea that they only supported such ideas because 'muh freedom, muh papal tyranny'.
