No, the argument is totally valid.
If two believers interpret one “divine” message to mean opposing things, in the full innocence of their faith, then the failure is on the entity making the message. Human whim is such a big factor in interpreting such vague and self-contradictory messages that people have lived and died fully believing they interpreted right, and the other, wrongly. Who is the arbiter? Other humans? Pathetic.
Your counter against the above is ridiculously nonsensical, and not fully thought through.
“No, the argument is totally valid.”
Notice though that your argument is so valid that you have to make an assertion that it is, followed up with what is basically just a repetition of what you said before followed up with chest thumping, without actually replying to anything I said.
“Who is the arbiter? Other humans? Pathetic.”
Why do we even need an arbiter? That’s more your problem, since you, being blinded, are incapable of understanding the scripture for yourself, and so you cannot come to a position unless someone tells you what to think.
