Hi Spud,
I didn't say you were trying to justify slavery. I said you were trying to justify the unjustifiable. Not slavery, in this case, but the abject immorality of (parts of) your so-called good book. (The qualification is in deference to Dicky Underpants who seems to know what he's talking about.)
It can be hard to understand your points, as words' meanings seem fluid to you. For example, when you said that "every inclination of the human heart" was towards evil, because that's what it says in the Bible, you didn't mean every inclination of human beings is evil, you mean something bizarre, obscure and totally unexplained about 'evil' inclinations originating somewhere different from 'good' ones.
It's easy to sound like you're giving answers when you don't need to be consistent, logical or clear. Some of them even sound quite impressive if you don't think about them too much. Or at all.
And that, my Liege, is how we know the world to be banana shaped.
