The error of the Obergefell decision was in the remedy it applied. Rather than come up with a ludicrous justification for forcing every state to change its marriage laws, the Supreme Court should have just struck down every provision of every Federal law that applies to married couples. That would simply mean the end to such tax provisions as "married couples filing jointly" and special treatment of spouses under deferred retirement plans and estate tax laws. That's it.
Interestingly, I can easily see us getting to the point where some states simply stop recognizing ANY marriages -- and treat "marriage" as nothing more than a contractual arrangement. That means you can be "married" to one spouse, a dozen spouses, or even 35 spouse and six pets. Let the retarded mutants on the Supreme Court figure out how to deal with that sh!t.
It all started with the IRS trying to preserve/coerce culture with tax laws.
If you are going to make people pay taxes, just make them pay taxes based on raw data like income. This is why I hate tax incentives like tax credits.
