Lets look at the verse
"those on whose part you fear desertion,"
Fear is the word used or suspicion could also be used.
So let me ask a question.
If its OK to beat a women because you fear disobedience or sexual misconduct from her could you also beat her if you saw her committing adultery and banging the next door neighbor in your bedroom?
Yes or no?
I'm afraid you are still committing the same logical fallacy of circular reasoning. You are trying to prove your point by arguing that the Qur'an wouldn't contradict itself or that the Qur'an would not be inconsistent or illogical or incoherent.
Maybe that's because you are used to discussing these points with Muslims who also believe the Qur'an to be the work of a divine and infallible God.
However we don't believe the Qur'an is infallible. Quite the contrary. We believe the Qur'an is the very fallible product of a human author - from the 7th century.
So it makes absolutely no difference to us if the Qur'an is inconsistent or contradicts itself.
In fact that is par for the course for us.
Also you have yet to respond to the glaring contradiction between an All-Merciful God and Excessively cruel torture. As I said before, this has got to be one of the most blatant contradictions of all time.
You can't be "Most Merciful of those who show Mercy" while also torturing people in the most insanely grotesque and excessively cruel way - keeping them alive just for that purpose - burning off their skin and replacing it - so they can feel the horrible agony over and over again.
And please don't tell me I am just focussing on a word or a verse.
As I said perviously the Quran spends an enormous amount of time detailing the horrors of Hell and threatening disbelievers with it.
