Why MUST it be called marriage?
I wouldn’t mind some sort of civil union, with a big asterisk. The consequences... divorce law, pooling of assets, access to HIPAA medical info... aren’t that disruptive. But it isn’t marriage... family, usually with the goal of reproduction. Why pretend?
If fedgov can just take over a states rights issue, what’s to stop it from declaring all state CCW laws invalid? What’s stopping them from declaring any laws they don’t like at the state level, invalid?
And what will be the point of individual states then?
This is where it leads. This would lead to internal war.
