In the article "US Violence Abroad Begets Violence at Home" on Ron Paul Institute, in response to the shootings in Las Vegas, Jacob G. Hornberger lays out the theory that American violence abroad begets American violence at home. This comes in 2 forms, either in terms of retaliatory terrorist attacks or in terms of violence carried out by Americans who have become desentisised to the taking of human lives.
Novus Ordo Watch has a good article on Pope John XXII, showing that accusations of him having committed heresy are dubious since the issue he brought up was open to theological debate. Pope John XXII is often used by those who want to assert that a pope can fall into heresy as an example of this case, and many are drawing parallels to him and Bergoglio.
