What’s wrong with that?
Seriously, either we believe in state rights and sovereignty or we don’t. Does our support for state rights evaporate when the states do things we don’t like? If it does, then that’s not support for state sovereignty - it’s support for particular policies.
I’ve been saying this for a while now. If you support the right of a state to set its own policies regarding marriage, then you necessarily oppose Loving v. Virginia - whether you think the Virginia law itself was good or bad.
This is like support for free speech. Do we support free speech only when it’s speech we agree with? Of course not. Do we support state sovereignty only when it results in our preferred outcome? I certainly hope not, because that’s expediency, not principle.
Or you believe that states have some rights but not all rights. To believe that Loving was wrongly decided you'd need to believe that the 14th Amendment doesn't mean what it plainly says.
