Speech is a choice, thoughts to desires and actions to habits leading to character and then nature. We have a choice to decide what we take from the society, to investigate if our “nature” is not rooted in someone or some group of person’s desired outcome of human lives.

So you believe it is your destiny or nature to be gay? Not that its your nature. The question should now be, is my belief system justified by the standards of requirement for continuance of life, society and the human race.
Is it a duty for us all to prevent extinction of human? Probably dragons fought for gay rights!
