Because you asked someone to go back and answer your 'point' in #1206...
In Moses' time, Israel were simply told not to have homosexual relations and expected to obey, because they had experienced God first hand.
Moses almost certainly is a mythical figure, there wasn't really a Moses.
When it comes to Paul writing to the Romans, he uses a concept they already understand when talking about sexuality - the argument from nature.
You don't 'understand' the naturalistic fallacy if you deploy it thinking it's a point, that's part of why it's a fallacy. The naturalistic fallacy says that because what you say upsets me I should hunt you down and beat you to a pulp because that's how primitive creatures establish primacy - the whole point of morality and humanity is to try to rise above baser instincts where they are problematic.
He says that because mankind worshiped created things rather than their creator, God gave them over to both excessive lusts and unnatural desires.
And Gandalf says that you shouldn't trifle in the affairs of wizards, but that doesn't make it true either. The argument from authority is really, really threadbare when your 'authority' is make believe.
Homosexual desires are unnatural.
Except that it isn't:
No species has been found in which homosexual behaviour has not been shown to exist, with the exception of species that never have sex at all, such as sea urchins and aphis. Moreover, a part of the animal kingdom is hermaphroditic, truly bisexual. For them, homosexuality is not an issue

https://en.wikipedia.org/wiki/Homosexual_behavior_in_animalsShoes are unnatural, should we all go barefoot? So, when you look at it, is typing on the internet. Except that... we're human, we're tool-making, consciously-thinking, morally-capable independent animals. If we make a decision to rise above base instincts, that capacity is part of our nature. Even if the rest of the animal kingdom were suppressing the natural expression of homosexual behaviour, which they aren't, us choosing not to is entirely natural FOR US.
Steve has already explained why, but to expand a bit, the man and the woman have different roles, in that the man penetrates and the woman is penetrated.
Your sex life must be so, so limited if you thank that's the whole picture. Sometimes sex isn't penetrative at all, sometimes everyone 'get into it'... who are you to tell someone else what's the 'correct' way for them to find or give pleasure? Next you'll be telling me sex is only between two people at a time...
Homosexual acts reverse those roles, so that men play the role of the female and vice versa.
Can you explain who's being penetrated by two tribbing lesbians, please?
This is what makes the acts dishonoring, and thus, morally wrong.
Dishonouring who? How? If a straight man is pegged by his straight wife because they're both having fun is that 'morally wrong' and 'dishonouring'? Is it more morally wrong for you to try to impose on them your sexual preferences in the guise of 'sin police' or for them to enjoy themselves in private in a way that has absolutely no negative effect on anyone?
So, in summary:
"Homosexuality is unnatural" - not it isn't, all sorts of animals do it.
"Homosexuality in humans is unnatural" - no it isn't, humanity has a natural capacity to rise above base instincts.
"X is unnatural, and therefore morally wrong" - that's the naturalistic fallacy
"Moses said homosexuality is wrong" - Moses wasn't real.
"Someone in my holy book said homosexuality is wrong" - someone in your holy book could be wrong, given they thought it was Moses that seems likely.
"God say it's wrong" - That's just an appeal to authority to try to enforce one of those subjective moral judgements that religion is supposed to be so set again.
On a grade of 1-10 that arguments scores an F- 'Must try harder'... Except, don't try harder, just try to manifest that 'God is love' mentality and forget all the bronze age homophobic nonsense that's been wrapped around someone's attempts to marshal society into a breeding programme for religious soldiers. If two people care for each other, what they do or don't choose to do in a private setting isn't a moral question, at worst it's a healthcare question and at best it's something to be happy for them about.
