A personal story comes to mind. I know a Benedictine monk (brother, not a priest) who considers himself homosexual, but not practicing, and told me so. I assumed as much, considering what else he'd told, and a few mannerisms. I was somewhat offended that he told me, since I cared more about what he contributed to his Order, which was considerable; he was a music teacher, organist, even wrote music. Having known many priests in my life time, and assume all are/were celibate, I prefer to view them in that manner, than having sexual preference, excluding pedophilia.
According to the homosexual community, they are JUST like us, except that they are attracted to members of their own sex. If that person is living a celebate life, then why would he wish to identify with that community?
