How about killing them?
The most complete set of norms against homosexual practices in the medieval era is contained in the canons approved at the Council of Naplouse, assembled on January 23, 1120 under the direction of Garmund, Patriarch of Jerusalem, and Baldwin, King of the same city. On that occasion, a sermon was preached about the evils that had befallen the Kingdom of Jerusalem. Earthquakes, plagues, and attacks by the Saracens were judged as a punishment from Heaven for the sins of the people. As a consequence, the Council issued twenty-five canons against the sins of the flesh, four of which related to homosexual practices. Death at the stake was decreed for those convicted of those specific crimes.
Note the date: After the Great Schism (A.D. 1054). Unlike Rome, the Orthodox enforced rigorous discipline.
The Orthodox had the right ideas.
It seems modernity destroys in the long term.
