Don't want to be that guy but you did cherry pick a little there, the Bible, even in the NT, is clear enough on the ultimate fate of any practicing homosexual.
Corinth 6:9-10: 9 Or do you not know that wrongdoers will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor men who have sex with men[a] 10 nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God.
Now it does say people who commit these sins can be cleansed, however it clearly relates to them leaving such sin behind. Any practicing homosexual who isn't going to give up a sexual relationship isn't getting past those pearly gates.
Then there's Pauls huge rant about the variety of sinful people in Romans, where as part of it he mentions the sinful actions of Polytheists including..
"Because of this, God gave them over to shameful lusts. Even their women exchanged natural sexual relations for unnatural ones. 27 In the same way the men also abandoned natural relations with women and were inflamed with lust for one another. Men committed shameful acts with other men, and received in themselves the due penalty for their error."
So he's clearly not particularly keen on homosexual relations, which are of course in his list of actions (including disrespecting parents, greed, malice etc) which....
"Although they know God’s righteous decree that those who do such things deserve death, they not only continue to do these very things but also approve of those who practice them."
Which would suggest Paul is reminding us that the Old testament is not in fact outdated, since it makes up half of your Scripture and has the words of your God, where in Leviticus he clearly says anyone practicing homosexuality should be killed.
I appreciate Jesus coming may have changed some things, albeit Jesus himself did say he had not come to change his fathers laws, but how can you discount the words of God himself in the OT? Unless God changes his mind, which is odd for an eternal perfect being. Also the sticky issue of the ten commandments being introduced in the OT...that half of the book does contain some useful stuff.
Obviously I think people who pick the peaceful loving verses are great, but it doesn't change the fact that if you took the decrees of YHWH himself at face value, you'd be hard pressed to allow homosexuality to be legal, even if you did decide the death penalty was overly severe and it was better to let God decide life/death.
