It is dangerous to make false claims that are easily verifiable... and that's the biggest bunch of revisionist bunkum I've ever read.
First, the Papacy had enormous influence over "rulers of the day." So, when, for example, Innocent III publicly ordered a crusade to exterminate the Albigensian heretics, the more pious "rulers of the day" were happy to comply.
Second, you're forgetting that the Pope himself was one of the "Rulers of the Day." Up until the unification of Italy in the late 19th century, the Pope controlled a country, the Papal States, in which the death penalty was frequently administered for heresy. One, of many possible examples: the scientist Giordano Bruno, burned at the stake by the Church, in Rome, in 1600.
Maybe you should learn a little more about what you're talking about before you go pontificating (no pun intended) to others.
that’s but a nice tagline....
