That message sounds much more like the Pharisees than anything else. "Immoral lifestyle"? According to who, Paul? (Remember, Paul was not only a Jew but a very prominent Pharisee before starting to preach Christi-SCAM-ity). And, one thing is certain. There is nothing inherently immoral with someone that chooses homosexuality, even if one could choose it, any more than it is immoral for me to choose high color temperature LED lights instead of the standard 2700 K bulbs. I see nothing wrong with abiding by what you, as a free human being, choose to do.
What I do see as immoral is the hang-ups that these religions impose on people. Judaism does it. Islam does it. And thanks to sexual-repression-and-asceticism-is-virtue Paul, Christi-SCAM-ity does it. All three impose strict rules with sex. All three make people repress normal bisexual expressions. Human nature is bisexual, and usually heterosexuality dominates. But, when they make so many rules with sex, children are taught that heterosexual contact is "naughty" (ever notice the big fuss with sneaking into the opposite sex bathroom). They are later taught that homosexuality is such a horrible sin, that it will result in divine punishment. As such, people's dominant sexual orientation is occluded and no one ever gets to properly express it.
Additionally, these religions pose so many barriers against sex. Because of such religions, we do not have perfect birth control. Because of such religions, VD hasn't been eradicated. Because of such religions, people carry sex hang-ups into marriage and do not fully enjoy them. Because of such religions, they marry someone they are marginally attracted to "because it's a sin to enjoy it too much" and then are trapped. I view it as extremely immoral that religion imposes this kind of rubbish on sexuality.
And, speaking of immorality, since when does the Talmud, LIE-ble, Quran, or Book of Mormons utter a peep against torturing non-believers, slavery, and even genocide? You don't even need access to Talmud, Quran, or Book of Mormons--the ubiquitous LIE-ble is full of genocide from Joshua through the end of the Old Testament. It picks up the ball with the King of Sexual Hang-ups Paul, with hell threats for those who do not comply. Revelation, right at the end of the so-called New Testament (Christian) part of the LIE-ble, glorifies genocide for all those who do not comply with this foul religion. All three major right-hand path religions, and any once-pagan religion they have touched, share these problems.
If this message could be classified as Pauline Christian (as if homosexuality is immoral but torturing and enslaving non-believers wasn't), I am surprised that more people don't simply blow off the whole of religion entirely or turn to its adversary and mankind's Friend Satan. At least Satan doesn't care what you do in the bedroom but is against torturing and enslaving non-believers or threatening believers with damnation to get more out of them.
