Why do you personally care what two consenting gay adults do in their own home? Please be very specific, and if you think it harms you in any way, please explain why. Please be more specific than "it just isn't right". What actual damage does it do to you?
Where did you get the idea that gays should be prevented from being gay? Either someone taught you or you came to the conclusion yourself from logic. Was it the bible or your religion? Was it your parents? Who put the idea in your head? If you came up with the idea yourself please explain why you came to that conclusion.
