I think we should all be allowed to marry who or whatever we want whenever we want and however many we want.
So aren't we also discriminating against polygamists since it is still illegal? Who are we to say how many wives or husbands someone can have? I think we should lift all restrictions on marriage in any way shape or form. I should be allowed to marry a tree, or a pancake, or a chicken if I want to as well. Or all 3. Maybe not with all the benefits of a married life (like tax breaks etc.), but why restrict it. It should be recognized if we so choose.
I've got a better idea. A constitutional amendment prohibiting the Federal government from regulating "marriage", which I would argue is a tenet of "religion".
. . . . . . oh. . . . I see . . . . . it's already there, twice. Congress shall make no law regarding establishment of religion, and the tenth amendment which proscibes the Federal government from assuming powers not specifically delegated to it by specific provisions of the Constitution. . . . . .
individuals already have the power of contract to define interpersonal relations/responsibilities, and we shouldn't let States infringe on that.
people already have the right to enter "contract" arrangements, and even states can't infringe on the right or power to contract between individuals.
