You admit in the bolded that you think interracial marriage bans are constitutional.
Only if they're unconstitutional could the states be forced to give them up, and you say the Federal government doesn't have that authority.
Right. States were "forced" to accept them by the SCOTUS. All bans were struck down, not ones that prevented a marriage in another state from being recognized.
Did the Judicial Branch have that authority
no
or was it "judicial activism"?
Yes, and for that reason. The Federal government has no Constitutional authority to either force or deny interracial marriage or gay marriage, therefore it is prohibited to the Federal government. Judicial activism pure and simple.
Okay, let's say they never ruled. Should legal marriages (whether cousin, interracial or same sex) performed in one state have to be recognized in another state that did not choose to give their citizens equal protection under state law?
