Wow, back, you really do get a hard-on from being provocative, don't you?
You are dealing in a false dichotomy here: either we accept only the NT and see the OT as worthless (as Marcion did, that position was decisively defeated in the 2nd century), or we see the entirety of the Bible as inerrant, inconsistencies and all.
But those are not the only two possibilities. A third is that we can take the Bible as a whole, and see it as 'what God wants to tell us'. I am going to quote here from a recent book by Rowan Williams, who puts this better than I can:
'How can [the whole Bible] be addressed to us? The simplest way in which we can understand this is the one I have already hinted at: this is what God wants you to hear. He wants you to hear law and poetry and history. He wants you to hear the polemic and the visions. He wants you to listen to the letters and to think about the chronicles. And from the earliest days, Christians, like Jews before them and Jews now, wrestle with how you can actually say 'This is the word of the Lord,' the communication of God. You cannot just go by surface meanings because surface meanings do not immediately help with understanding why God wants you to hear it. This may be the word of God, but why is it important to God that you know it?' (Rowan Williams, Being Christian, pp. 25-26)
So it is not that God approves of everything that happens in the Bible the floods and the genocides and the details of the law but that we need to see these as the stories of how people responded to God at that time. Williams asks: 'Are you capable in the light of the Bible as a whole of responding more lovingly or faithfully than ancient Israel?' (p. 28)
