You unfortunately have to start with the premise that the KJV bible, along with others have misrepresented the original language and intent of the scripture either knowingly or unknowingly and we in the 21st century have put too much emphasis on the cultural norms of a tribe from 2500 years ago. We know slavery is condoned in the bible but as a civilized culture have worked beyond that ignorance. No true Christian today would support the literal, biblical, word on slavery and we should not do it either for homosexuality.
The most well known passages that seem to be against homosexuality are as follows:
Genesis 19:1-5 - Story of sodom and Gomorrah - but consistant translation of the original language points to God condemning the people not because they were homosexual but because they were cruel, selfish and showed no mercy or compassion to others as shown in Ezekiel 16:49-50
Leviticus 18:22 and 20:13 - Holiness Codes - "You shall not lie with a male as one lies with a female; it is an abomination" and "If there is a man who lies with a male as those who lie with a woman, both of them have committed a detestable act; they shall surely be put to death. Their bloodguiltness is upon them"
If you look at the context of Lev 18:21 you will see that it sets up the transition to forbidding ritual child sacrifice (to the Pagan god Molech). The verse also forbids blasphemy against Yahweh. Moving sequentiallyto 18:22 the translation also focuses on forbidden idolatrous activity in a Pagan temple (male protstitution/religious sex at another temple). And Lev 18:23 continues onto known sexual idololatry within other religions, "'Do not have sexual relations with an animal and defile yourself". There is a clear distinction between the moral code of who you should not have sexual relations with in Lev 6-20 and those that follow as temple idolatry.
As well, the word "abomination"in those passages is from "Tōʻēḇā" which the bible also uses in context to dietary restictions, temple prostitution, etc
For Lev:20:13 - This passage does not refer to gay sex generally, but only to homosexual prostitution in Pagan temples. Some fertility worship practices found in early Pagan cultures were specifically prohibited; ritual same-sex behavior in Pagan temples was one such practice.
Our societal, sexual, and psychological understanding of homosexuality in a 21st century culture VS 500 BC tribal culture should lead all christians to be more temperate in their understanding.
As well, here are the rest of the Mosaic code that should be followed literally, if you also condemn homosexuality:
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),
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, lobster).
Last, Jesus says nothing about same-sex behavior although Paul is referenced in 1 Cor. 6:9-11 as "Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind, Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God." . The term "abuseers of themselves with mankind" its often taken to mean homosexual, but Ii Paul wanted to refer to homosexual behavior, he would have used the word "paiderasste." That was the standard Greek term at the time for sexual behavior between males. Instead he used, "arsenokoitai" which may translate to male prostitutes or pedophiles
