Its not only the Catholics who hate gays:
Leviticus 18:22 is translated: "Thou shalt not lie with mankind, as with womankind: it is abomination."
Ezekiel 16:49-50
49 " 'Now this was the sin of your sister Sodom: She and her daughters were arrogant, overfed and unconcerned; they did not help the poor and needy. 50 They were haughty and did detestable things before me. Therefore I did away with them as you have seen."
"We also sent Lut : He said to his people : "Do ye commit lewdness such as no people in creation (ever) committed before you? For ye practice your lusts on men in preference to women: ye are indeed a people transgressing beyond bounds." Qur'an 7:80-81
"Both of them fornication and homosexuality involve immorality that goes against the wisdom of Allahs creation and commandment. For homosexuality involves innumerable evil and harms, and the one to whom it is done would be better off being killed than having this done to him, because after that he will become so evil and so corrupt that there can be no hope of his being reformed, and all good is lost for him, and he will no longer feel any shame before Allah or before His creation. The semen of the one who did that to him will act as a poison on his body and soul. The scholars differed as to whether the one to whom it is done will ever enter Paradise.
Gampopa (12th century), one of the main early masters of the Kagyu school of Tibetan Buddhism, followed the Indian Buddhist tradition, starting with the third-century Hinayana texts of Vasubandhu, that oral and anal sex, whether with a man or a woman, are violations of the third precept regarding inappropriate sexual behavior. Longchenpa, the 13th century founder of the Nyingma school, citing the third-century Mahayana texts of the Indian master Asanga, elaborated that inappropriate sexual behavior also include the hands among inappropriate parts of the body for sexual activity.[28] Subsequent Tibetan masters from all four schools of Tibetan buddhism accept all these specifications as delineated in the earlier Indian Buddhist texts.
The current Dalai Lama follows the traditional Tibetan Buddhist assertion that inappropriate sexual behaviour includes lesbian and gay sex, and indeed any sex other than penis-vagina intercourse with one's own monogamous partner, including oral sex, anal sex, and masturbation.
But in the same vein:
The Torah is composed of the first five books of the Hebrew Scriptures (Old Testament). It contains numerous laws which make up the Mosaic code. Rabbi Simlai wrote in the Talmud (Jewish traditional commentary about the Hebrew Scriptures) that God gave 613 commandments to Moses. One list finds 3 commandments in Genesis, 111 in Exodus, 247 in Leviticus, 52 in Numbers and 200 in Deuteronomy. These included 365 prohibitions -- a number equal to the nominal number of days in the year. Also included are 248 positive commandments which Rabbi Simlai said corresponded "to the number of organs and limbs in the human body." Hundreds of these dealt with animal sacrifices and other topics that are not currently practiced. That leaves about 300 commandments that can be practiced today.
The Holiness Code in the Torah permits:
slavery (Leviticus 25:44)
The code requires:
A child to be killed if he/she curses their parent (Leviticus 20:9)
All persons guilty of adultery to be killed (20:10)
The daughter of a priest who engages in prostitution to be burned alive until dead (21:9)
The bride of a priest to be a virgin (21:13)
Ritual killing of animals, using cattle, sheep and goats (22:19)
Observation of 7 feasts: Passover, Feast of Unleavened Bread, Feast of Firstfruits, Feast of Pentecost, Feast of Trumpets, Day of Atonement, Feast of Tabernacles (23)
A person who takes the Lord's name in vain is to be killed (24:16)
The code prohibits:
Heterosexual intercourse when a woman has her period (Leviticus 18:19),
Harvesting the corners of a field (19:9),
Eating fruit from a young tree (19:23),
Cross-breeding livestock (19:19),
Sowing a field with mixed seed (19:19),
Shaving or getting a hair cut (19:27),
Tattoos (19:28),
Even a mildly disabled person from becoming a priest (21:18),
Charging of interest on a loan (25:37),
Collecting firewood on Saturday to prevent your family from freezing,
Wearing of clothes made from a blend of textile materials; today this might be cotton and polyester, and
Eating of non-kosher foods (e.g. shrimp). This prohibition has been satirized on the God Hates Shrimp website.
I dont adhere to most of the Mosaic code, so why does homosexuality have special pertinence? To be fair some who believe God commands not to have homosexual relations point to Romans 1:28.
Personally, I dont know. I dont hate gays/lesbians, like jet says, I try to love all people, but I am not sure if homosexual relations is something my zen teacher, Jesus, would agree with. There has been a lot of advancements recently in homosexuality equality...again I try to love everyone to the best of my ability, I allow myself to make judgements I am not some hedonistic sophist. I need to be honest with myself and others and maintain an ethical and intellectual cohesion. To me a hedonist is the equivalent of an intellectual slime, might as well be a nothing, because as a hedonist you are nothing, you accept everything, judge nothing, and are incapable of forming your own intellectual arguments, you go where the masses take you, you cant think for your self.
That being said, I am not anti gay, I am pro Jesus.
