There is no reason for anyone to fedpost and no one is insisting on that. 

If Texas continues as they currently are, then the people of the US (Texas included) will soon cease to exist… it’s not debatable. This has nothing to do with Texas owing anyone anything. It’s called self-preservation.

No one says securing a border would be easy. Texas can’t ask for help in doing so before they begin enacting border protection policies. Everyone knows what happens once state policies are put into place and it’s not fed-posting to point out the obvious.
