Polygamy is actually an Old Testament practice, which was never challenged in the New Testament.
Women and men are free to do as they like, which is less demeaning than demanding that they conform to some other person’s arbitrary societal expectations. Whatever that may be, it is not freedom.
(Mormons are still not playing with a full deck of cards, but not for this.)
No polygamy was NOT an Old Testament practice.
Before one says that, they should actually read the old testament AND understand historical context.
Polygamy is ruled out in that, number one, God made them "male and female," not male and females, and, secondly, if you divorce and remarry, you are committing adultery. If polygamy was acceptable, it would not be a sin to remarry. She would just be your second wife.
But from the beginning of the creation God made them male and female. For this cause shall a man leave his father and mother, and cleave to his wife; And they twain shall be one flesh: so then they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder. And in the house his disciples asked him again of the same matter. And he saith unto them, Whosoever shall put away his wife, and marry another, committeth adultery against her. And if a woman shall put away her husband, and be married to another, she committeth adultery. (Mar 10:6-12)

Every instance of polygamy in the old testament produced misery and Jesus was blunt about marriage being one man and one woman.
