“So spare me the BS about polygamy being OK with God. Show me the scripture where God suspends the Ten Commandments...”
While you’re looking at the Ten Commandments, flip to the next chapter for a sec, where God is setting down ordinances. Exodus 21 is a pretty interesting chapter. Among other verses, check out 10: “If he take him another wife; her food, her raiment, and her duty of marriage, shall he not diminish.” Wouldn’t it have been so much easier just to say, “He shall not take him another wife?”
Yes, indeed, Exodus 21 is "interesting." Tell us...since Exodus 21 also sets up minimum standards for treatment of slaves, does that then mean you would claim that the Bible advocates slavery? (keep in mind that not all slavery in the Biblical era was American-style slavery...some of it was multi-year economic debt repayment--temporary bond servants).
Moses' Five Books neither encourage/discourage slavery. Exodus 21:7-11, along with Lev. 25:44-46, establish basic treatment standards. Your reference to Ex. 21:10 no more reinforces the practice of polygamy than it would slavery...and the fact that you isolated that verse from a 4-verse context of slavery--and didn't mention that little fact--is a form of half-truth deception if you did that purposely.
