My stance is that to me that's not relevant. If you believe or not in Jesus, how is his sacrifice affected by the position in which he was murdered?
Jesus dying on a cross+ doesn't add up. It does not fit with the irony of the Bible; take for example the copper serpent that moses lifted up in the wilderness. It wasn't on a cross. That is just one example. Cannot be explained has to be understood. It must have worked out that Jesus died on a pole. No other way could fulfill the ironic poetry of the Bible.
