“A gay priest around teen boys is about as safe/unsafe as a straight one around teen girls.”
Someone who defines himself as a homosexual or gay defines himself by sexual acts that are sinful. Many Catholic boys have had bad experiences with homosexual priests beyond homosexual rape/seduction. Homosexuals teach and encourage a value system that is contradictory to Christ’s teaching.
Regardless of how they “define themselves,” the Bible doesn’t say anything about that. Only the act.
