Gov. Shutdown?

Children cannot consent; that is how gay marriage is different from pedophilia. In theory, I don't see anything wrong with polygamy. Many religions have long accepted polygamy. The problem with polygamy is actually the religious component that's usually involved. Women (or girls) are often pressured by their families and religious communities to enter polygamous marriages or face excommunication and ostracism. With incest, the concern is the increased chance of genetic abnormalities; although, it's been debated whether the increases are significant.

That echoes exactly what my arguments against incest and pedophilia would be. Those two things are in no way similar to gay marriage.
