The analogy also fails because it requires dividing humans into different types of humans. Fundamental rights are required for all humans, not just for specific types of humans, though some keep trying to repeat that mistake throughout history. Our government was intended to correct that tradition of injustice. So regardless of ability to reproduce, marriage remains a fundamental right of the individual.<quoted text>
Oh but it can, based on intent....Man, you are really f(_)cked up..no one is 'demanding a heterosexual couple bear children'...I certainly don't want YOU to have ANY! If anything you're the one harping that reproduction be a requirement for marriage, which is totally discriminatory and asinine.
The only major restrictions are age, informed consent, not close blood relative, or currently married. Gender is not a restriction, and requiring one of each serves no purpose beyond harming same sex couples.
