That clause is exactly a forswearing of power not an exercise of power.
"Section 3 of DOMA codifies the non-recognition of same-sex marriages for all federal purposes, including insurance benefits for government employees, Social Security survivors' benefits, immigration, and the filing of joint tax returns."
You can argue that the federal government shouldn't provide any employee insurance or Social Security survivors' benefits, or regulate immigration, or collect income taxes - but if you grant that any of those are as a whole within their powers, you can't then argue that setting specific policies in those areas is outside their powers.
As for abortion it also is not a federal issue it is not covered by the Constitution it was made up by the USSC.
And since the federal court made it up and is unwilling to unmake it, only action by the other federal branches can rectify that - those actions are in defense of the Constitution not in violation of it.
So you are ok with the feeds doing whatever they want to do. So you like a nanny state, you know the Constitution really means nothing anyway.
Hysterically misstate much? Try addressing what I actually posted instead of flailing at your cartoonish straw men.
Marriage and Abortion are not covered in the Constitution and they should not be allowed to mess with either issue.
I have arguments, you have bumper stickers - I'm content to let readers decide who has the better of this debate.
Passing an unconstitutional law is wrong period. Saying well it is to correct something else does not make it right, it is still unconstitutional. These are things that have lead us to this point, instead of correcting the problem they pass a law that affects everything except the problem. If the USSC does something it should not then Congress should address that. Not pass a law that affects us and not the USSC. They need to treat the problem not the symptom.
