The statutes from the 18th century related to military spouses are academic, as far as I'm concerned ... because personally, I can't imagine why any self-respecting man with a Christian world view would ever put his life and safety (and a potential widow's well-being) in the hands of the government in a nation as nihilistic, depraved, and openly hostile to Christianity as ours is.
Those statutes have always and continuously been maintained and updated, and are still there, because they are necessary, and completely current and relevant.
But thanks for the bile about America and our fighting men, who actually tend to have that “Christian world view” that you imply they don’t have, they also have self respect.
You would deprive them of what they need to maintain and protect their families, by either taking it all away from them, or making it so overburdened with polygamy and personal relationships that it couldn’t work.
