Libs best analogy is the interracial marriage case,
Courts wont let states ban interracial marriage,
So now gays are the new blacks, if you marry heterosexuals then you must marry gays, to each other, or its discrimination against gays.
Gays=new blacks = same sex marriage.
Same thing applies with Marriage in all cases as its not a right nor a privilege and is an establishment of religion, the Federal Courts, congresses etc lack jurisdiction on Marriage - the 14th does not apply.
