How can anybody be "proud" to deny the facts of reality? Man + man or woman + woman are incompatable sexually. Don't you remember your anatomy classes in grade school? Being proud of your homosexuality is like being proud of willfully doing other absurd behavior, such as shoving food in your ear, sticking your finger in an electrical socket, or driving your car into a lake. Each one of these examples deny the facts of reality and serve no purpose whatsoever.
