Marriage will be meaningless only if you let it be.
Yup. Marriage will only be meaningless if you rely on whatever mutating definition the state uses to define marriage for itself currently. Sad thing is, many have conditioned to do exactly that. To the state in the modern era it’s always only ever been what judges, pols, or the voting majority think about marriage at any one time. Thus banning interracial marriage at one time, civil divorce and remarriage, then easy civil divorce and remarriage and now ‘gay marriage.’
