First, "gαy sex" -- It's perverse and disgusting, contrary to natural and divine law, gravely sinful and mortally so; it can and will lead souls to the deeper levels of eternal Hell, forever and ever. In times past, Catholic princes, as the civil guardians of their subjects' souls, had not only the right, but the duty, to punish ɧoɱosɛҳųαƖ acts, up to, and including, public immolation.
Now, as for ɧoɱosɛҳųαƖs themselves, if they are willing to lead a completely chaste lifestyle in complete continence with regular, if not frequent, confession, then, yes, they should be allowed to receive the Holy Eucharist, and, indeed, serve the One True Church, the Catholic Church, in a capacity as laypeople, but never in the capacity of Holy Orders.
BUT, what happened to,
"Don't ask, don't tell!!!"
If someone is gαy, then they do
not need to "advertise" that! The only people who need to know are their Confessors, and absolutely, positively no one else! In fact, it would be
sinful for someone who, through no fault of their own, had ɧoɱosɛҳųαƖs desires and/or inclinations to reveal such to another individual, let alone in the external forum! Such things belong in the internal forum, specifically, in the confessional, where the Seal will guarantee absolute privacy.
