A Question

A QUESTION....I haven't been following about that polygamist sect in Texas all that closely, so maybe I'm just not paying attention.

But I thought polygamy was illegal in most states. The charges of child abuse, which seem to have been dropped for the moment, were what the state chose to use. But if polygamy is illegal, why not use that?

And if polygamy isn't illegal, then what happens to the argument that gay marriage will lead to polygamy?
