Gregory Brower, the Arizona U.S. Attorney, said during a Senate hearing in 2008-JUL that there is no federal law against polygamy. He commented that the federal government has a number of traditional resources at its disposal to investigate polygamists, including FBI, Alcohol, Tobacco and Firearms, IRS, and other inspectors.
However, polygamy is illegal in all 50 states under state laws. - http://www.religioustolerance.org/polylaw.htm
According to the laws of all 50 states it would appear so.
Your point it not lost on me, but it in no way applies to my argument.
This does not mean we as Christians should support or condone it in anyway, period.
We can play a numbers game all day, but you will lose every time.
