DU-folk (and I'm sure they're far from alone in this) don't/won't comprehend what they've accomplished. The statutes and state constitution amendments the USSC overturned did not forbid, in so many words, same-sex marriage. What the USSC overturned was those states' definition of marriage. No definition, no standards really means no definition or standards! IOW, anything goes, up to and including whatever the judicial tyrants are willing to stomach!
Polyamorous? Poly-species? Marrying oneself? Marrying one's chair (was it Sesame Street that had the "Love of Chair" bit back in the mid 70s or so?)? Two words: Judge Shopping!
