Two thoughts, one pro-, one con-:
The Church in America is the epicenter and chief promoter of the feminist and homosexualist heresies. The Church in the world will not be free of these until the Church in America is purged. Presuming the Holy Spirit concurs, only an American can get to the bottom of the mess the American bishops have created.
OR
The Church is a worldwide Church, and is strong in most places (Europe and America excepted). A Pope from the developing world could condemn, and then basically ignore, the American heresy and build the future of the Church elsewhere.
Take a look around the world ... North America, South America, Europe, Australia ... this problem is global, not local.
