Now that is a novel idea. People could avoid inheritance taxes completely if a son married a dad, or whatever weird combination you can think of.
Do these people really not understand what they have done if polygamy is allowed? What if 1000 people want to marry each other? What if several people are married and some want a divorce but others don’t? What if A wants to still be married to B and C, but not to D and E? The legal complications on property, alimony, child support, child custody, inheritance, and a lot of other things would be enormous. It’s insane.
By redefining traditional marriage, they've opened the gates to hell. I say we shove them through it.
