Not likely that I will ping a pharisee like you, ever.
I have not appealed to the literal; text as you have to make an argument that you are both in error about the issue you raise and that you have a childish view of what the bible is about.
The bible is about realizing that we each need Christ, its not about looking for loopholes. Your reading of the bible on this issue shows a foolish man who steps past free gold in order claim a bucket of sand.
As to your specific question regarding adultery and polygamy, How do you reconcile the teaching by Jesus that if a man looks at another woman with lust he has committed adultery with her in his heart. How could any man obtain the second wife without violating this commandment of Jesus?
Your ignorance on what the bible is about is tragic. Your further ignorance of basic biblical themes that are consistent throughout in order to form your conclusions is negligence.
