A two-fer reply. I’m becoming more efficient. The Bible doesn’t call for destroying pagan artefacts. The Israelites were not ordered to remove ancient sites of worship, a la ISIS. We are talking about shrines and altars that were contemporary at the time. We’re talking about knocking over piles of stone and burning wooden poles, not blowing up 2000-yr-old temples. God called for this action to remove the temptation toward syncretism, combining the worship of Baal (and other gods) with worship of YHWH. As a matter of fact, Israel did not follow through, and they did end up chasing after other gods. The book of Hosea is a good introduction to the theme of Israel as “God’s unfaithful wife.”
Regarding your question on the “ideal,” you still seem confused on the difference between a statement that applies to a particular historical situation and a statement that is meant to be universal. As well, God’s communication with mankind always accommodates our historical situation and cultural development. (God did not reveal himself to ancient peoples in modern language and modes of thought.) The trick is to separate what is time-bound from what is timeless.
I suggest you try reading the Scriptures with your heart instead of your head for a while. Let the Word of God speak to your spirit and bring healing and shalom, rather than confusion and despair. Seek God, not intellectual puzzles. Just my 2c
