the normal status quo is man plus woman. It has nothing to do with state vs federal (for me anyway.) I simply see no reason for society to go out of its way to support every single oddity people can come up with. Especially since, if we deviate from the obvious norm once, then why not do it again? Why not legalize incest, provided both parties consent? Why not lower the age of consent to post-puberty, since they do it anyway? Etc. None of those things are "natural restraints" and all of them involve "natural attraction." If we revoke our purely man-made laws for one deviation, then all the others start asking for it, and the reasons for denying them become flemsy. Better to just not cross the line in the first place and have a set standard in my opinion. And that principle can apply to basically everything, not just this. It has nothing to do with "hating" gays, or wanting to deny rights, but rather having more concrete, set standards of life. Of course, as we become a more liberal society, my "archaic" standards will continue to get phased out in the name of goofy political correctness and an "everybody wins!" mentality.
But, as someone said earlier, it gets ridiculous having laws completely change from one state to the next. So as much as I would rather keep my conservative state conservative, I understand why the federal government steps in sometimes
