If we allow homosexual behavior to be accepted as merely one more alternative and accepted lifestyle, we are running the risk of having modern America degenerate into a sexual equivalent of Ancient Rome, Ancient Greece, or the Turkish Empire. Not very savory models to emulate. When I can no longer trust my son in the care of a Catholic priest, and when I am told I'm a horrible person for not OK'ing a gay man's taking my sons out on overnight camping trips, it's already happened. And it's not savory. At all.
You have become another victim of that bane of the late 20th and early 21st centuries - Moral Relativism.
Its the bitter fruit of the "If it feels good, do it" philosophy of the late 20th Century.
