DOMA was only bad because it was a poor substitute for a Constitutional amendment defining marriage as a union between a man and a woman. Without it, the existence of states that allow homo marriage will allow the degenerates to abuse the full faith and credit clause of the Constitution and force states that have banned it to recognize it. The degenerates will do this by lawsuit, and the only way to prevent that, is to either pass aforesaid amendment, or secession.
or impeach judges
Not quite, DOMA could have been protected from the Supreme Court by congress (see congress's ability to limit the cases the Supreme Court can hear) -- I'm of the opinion that DOMA was put in place specifically to force the issue into the Supreme Court — I don't think it was a coincidence that as the USSC eviscerated DOMA they also set up precident to deny standing to the people in general as well as declare that State Supreme Courts could not confirm/certify standing. Noth that this was just before they amended the rules so that non-lawers cannot argue their case before the Supreme Court.
DOMA was a big distraction, and you're falling for it.
