Having been raised in a hyper-conservative Evangelical Baptist church, I've heard sermons preached praising God for demanding the extermination of various ethnic groups who were in the way of Israel's attempts to conquer what is still Palestine. More than any of the contradictions you rightly noted, this behaviour of God's made me question, and then deny forever, His supposed mercifulness. The Amalekites, Perizzites, Hivites, Jebusites, and Canaanites were all wiped out on God's command. I believe these commands are the first recorded instances of genocide in human history. A God who can happily demand genocide is a God we can do without. https://religionnews.com/2015/01/12/god-command-genocide-bible/
