Sure, what I meant by meaningless is that it was lacking a 'higher' meaning. It's not important for my argument how you rate it morally, just whether it's at morally the same level as similar gay sex, which would be covered by axiom 2.
So as for the illness, again, that's not a moral harm inherent to gay sex, any more than "don't go skydiving" is a moral argument. It could be dangerous, so avoid it, isn't where I'd make a moral claim. But I get this is small compared to the moral argument.
As for morality, most of mine is contained in a basic libertarian philosophy, NAP, etc, and ensuring that others get access to similar rights as well. So very roughly, a Utilitarian maximizing freedom according to the NAP, rather than pleasure or something else.
As for Christian ethics, I do find it interesting, having been raised Catholic and having gone to Catholic school for years, so I do care about it in the intellectual sense, but not in the sense that Christian ethics binds me, unless I get converted to Christianity (the big road block there being that I don't seem capable of honestly believing in God, though admittedly I haven't given it much attempt).
EDIT: But as a thought experiment, let's assume that instead, that a person X has some morality that doesn't explicitly condemn gay sex, nor mandate no non-procreative sex. Under what circumstances would they come to follow axiom 2?
Here, we get to another crux.
In throwing out Christian ideology, it becomes not just necessary to throw out the immediately-visible moral laws...
It also becomes necessary to find a morally meaningful definition of 'harm.'
Okay, so you follow an ethos of 'there's nothing wrong so long as nobody gets hurt,' or some similar wording thereof,
Who gets to define 'hurt?'
Does the meth addict get to define it?
Does the heroin addict?
Does the 'minor attracted person' get to define it?
Part of the issue I have with secular moral systems, is that they aren't just taking God's place in defining morality, they also have to take God's place when they define
hurt.
And as we very,
very quickly saw, 'homosexual sex isn't harmful, because those taking part in it say it isn't,' was then replaced with 'large-scale surgical modification of bodies is helpful, not harmful, because transsexuals say so.'
...and yet at the same time, as we have seen in some of the attitudes
in this very thread, just
disagreeing with homosexuals about the ethics of their lifestyle is seen as 'harmful,' and some people think it's not just acceptable, but
virtuous to try to silence the voice of dissent.
These things cannot be separated from each other. By the same movement where you reject God for the source of moral law, you
also are moving the definition of 'hurt' from being in the hands of God, and into the hands of men. And as we have already seen not just in theory, but acted out repeatedly in our society, specific people
will seize this power, and use it to
destroy the lives of others.
Examples: The Covington Kids, women who have been kicked out of various orgs for objecting to 'trans-women' being in the womens bathrooms, women raped in prison by 'trans' women, Anita Sarkesian's victims, etc, etc.
