You "believe"?

The bible does not support monogamy over polygamy. We were simply raised to believe monogamy is normal, and never questioned it. But it is not mandated by the bible. The bible is not anti polygamy.

Give one bible quote to back up that claim.

Traditionally, polygamy was the norm. Just look in the bible.

"Traditional" marriage is actually between one man and several women. As our culture changes, so does our idea of what is "traditional"

The problem is people equate "normal" with automatically being good and "abnormal" as automatically being bad.
