Ok, let me try giving an example. Let's admit that the bible has the following passage:
But those mine enemies, which would not that I should reign over them, bring hither, and slay them before me.
I naively say, this is an immoral passage.
Now someone comes along and says this:
"heeey don't say anything bad about that passage, because it's all metaphorical you see, and your literal eyes can't see anything intelligent, KTHNKSBYE"
Another dude comes along and says this:
"Ease up, dude. You can't really criticize that because that passage doesn't really matter. What matters is the behavior of the believers"
And I say, what the ffuuuuuuuuuu????
