I flat out reject the absurd notion of "sexual orientation" - let alone the false notion that society must somehow cater to the self-indulgent whims of a few who have allowed themselves to be given over to whatever desires their bodies might crave, for whatever reasons such cravings may exist. Similarly, I would reject the notion of "beverage orientation" - unless perhaps a group of us who crave beer be successful defining ourselves as a special class of citizen deserving of special rights and treatment by virtue of our lagered emotions.
Homosexuality is gross self-indulgence. Nothing more. It's a behavior. It's perverse and deviant behavior. It's behavior that can be stopped and changed. And just because a few have given themselves over to it does not mean we need afford them special rights - shame and disgust, perhaps. Rights no - because sans the behavior, they have precisely the same rights right now the rest of us have.
