Sorry, but believing every single word in scripture is inspired in the face of obvious contradictions, what you are expecting people to accept is akin to what Catholics expect their people to believe in the eucharist, that despite all evidence to the contrary, and all logic and common sense, we literally eat God. You, by your literalist viewpoint, are expecting us to believe that one account is literally as true as the other; that in order to be faithful to God's word, we must believe that both accounts were equally accurate in every respect. Sorry, that does not wash. God does not expect us to lose all reason and common sense when asking us to practise our faith.
That God has allowed those contradictions to remain is beyond all question, and likely deliberately so. If God wanted no contradictions, He would have arranged such. That He has allowed this is proof that He uses mortal error prone human beings as His agents and representatives, despite their flaws, and doesn't overrule or interfere. As I have said before, these contradictions do not disprove the Bible as inspired, but reinforce it. Just as in life no two witnesses will agree perfectly on their account of any event, unless they colluded in their testimony, so the gospel accounts, though differing in detail, add weight of proof that these events were real. How many demoniacs isn't that important. The principle and concepts that the event brings to our minds are what was inspired to bring change and salvation to ourselves. Just as it is with the rest of scripture.
So who determines then which is the inspired words? You?
