Just because it's human nature doesn't mean it IS wrong, either.
Actually, we should be very uncomfortable around so-called "gαy" couples -- ɧoɱosɛҳųαƖity is revolting on a natural level, and even more so on the supernatural (spiritual) level.
God destroyed the cities of Sodom and Gomorrha because of the widespread presence of the "vice against nature" known as ɧoɱosɛҳųαƖity.
We are NOT supposed to destroy our natural sense of modesty, and we're NOT supposed to brainwash ourselves that 2+2=5, that up is down, or that ɧoɱosɛҳųαƖity is just fine.
It has nothing to do with fear, and everything to do with OBJECTIVE (same for everyone) morals. Something is either RIGHT or WRONG -- it doesn't vary by person.
Matthew
