States rights don't trump the Constitution, as was found in the Heller case you so helpfully supplied. The DOMA case was completely unrelated to any state's anti gay marriage laws and whether they were Constitutional so the SCOTUS could not make such a determination in that case. You are mistaken in what you think the DOMA ruling means in your state.
Heller was regarding a state / municipality could deny permits to lawful, eligible applicants.
SCOTUS ruled they couldn't
Based on the affirmation that the right was individual. Thus affirming the 2A individual right free militia connection in its decision.
SCOTUS did the same thing w/ DOMA.
Affirmation of states right. Shall I post the language from the majority again ?
