Being gay isnt immoral, that you perceive homosexuality as immoral is a consequence of your ignorance and hate.
And gays are not seeking approval from anyone, they are acknowledging the Popes appropriate concession that issues pertaining to privacy rights and equal protection rights are the purview of the law and public policy, not subjective, irrelevant religious dogma.
If an individual in ANY Christian church believes the Bible is the word of God, then they MUST believe that living a homosexual life style is against The Word of God. It says:
And God blessed them. And God said to them, Be fruitful and multiply and fill the earth and subdue it and have dominion over the fish of the sea and over the birds of the heavens and over every living thing that moves on the earth.
How does living a homosexual lifestyle meet obedience to this command?
I personally find the pope's tone on this quite refreshing as he says, in effect, "there are far more serious things to be worried about now." Good for him.
