Mainline Protestant denominations also once preached hellfire and brimstone but their teachings has been totally compromised. If you think the doctrine of Hell is not Christlike, you must have never read the Gospels.
As for the Inquisition, you speak with a forked tongue. You love to condemn the Church for its infiltration by homosexuals, but you also condemn the traditional means of rooting out infiltrators. Catholics await the restoration of the Holy Inquisition so that the homosexual priests and bishops may be expelled from office.
The office exists. The tools exist. What is missing is the will to enforce the written rules.
