Freedom wise; I'm all for it. It should be legal. I love freedoms! Equality, sharing wise; I'm against it. If it gets popular, it might create more problems than it's worth. I think we have examples of it already. Years back, all Mormons were polygamists, now only small excommunicated groups remain poly. I'd swear they have their black secrets, more than half of young men, or just men, can't find Mormon wives. They have to look for one outside and bring to Mormon faith. Mathematically speaking, if 50% of man have 2 wives then other 50 have none. This can't go on for long. If we had wars every generation and were losing half the male population every time, then yes it would make good sense.
