"Jesus would rather kill, not marry, gay people" - Franklin Graham

[The Industrial Atheist]

Killing others causes objective harm, the pain and suffering of both the person that it killed and their families and loved ones. Two men or two women having sex does not, unless you count a feeling that something is icky as objective harm.

That is a mis-characterization and I think you know it (feeling that something is "icky").   And I've been down this road before the presence or absence of objective harm, doesn't make something moral or immoral. It doesn't account for objective morality. Or say why it is wrong (only that it causes harm)    If you would like to make a thread,  we can discuss why you think it does and I think that it does not.

We could add the caveat of unjustified harm. I don't think too many people believe killing in self defense is immoral. But I'm pretty sure we were talking about murder the whole time.

I'll take morality based off of an idea of preventing unjustified harm to others VS obeying the alleged words of an alleged god that are also often not even consistent with themselves any day.
