But, like, to where would they be deported? That typically implies sending them back to their place of origin, but in this case they're almost always from the US. Perhaps exile would be a better term to use.
My proposal: exile them to Texas (let's call it a "Texile"), and then let Texas have that independence they seem to so strongly desire.
I say we find one of the most uninhabitable places and give them just a few acres. Texas has a lot of our resources. Let's carve off some section of North Dakota or a place like that, and make sure it has no minerals underneath the soil and send them there to enjoy their "freedoms".
