Unless, of course, I missed your other possible cryptic assumption that the word "marriage" has always meant more than "a man and a woman as husband and wife", which is even more errouneous then the former error, if it's possible for one of two errors to be "more erroneous" than the other.
Regardless, your hair-splitting diversion is simply that, an attempt to run from the fact that you are in error either way.
Reality remains that today's SCOTUS rulings were simply nothing but state's rights decisions, each one 5-4, and one along ideological lines.
There is no comment there one way or the other on the definition of "marriage".
"Marriage" remains what it has been for 12,000 years through the present, unchangable by nature: "between a man and a woman as husband and wife".
