Can we give Texas back to Mexico?

Sen. Lois Kolkhorst, R-Brenham, is congratulated by Sen. Don Huffines, R-Dallas,
after the passage to engrossment of the "bathroom bill" during a long
 session in the state Senate, on July 25, 2017.

What you need to know
"For the second time this year, the Texas Senate passed a version of the "bathroom bill," a measure regulating which restrooms transgender people can use. But senators didn't stop there, and after the marathon debate worked into the wee hours Wednesday morning to pass other items from Gov. Greg Abbott's special session agenda. Here's what you need to know: 
• The bathroom bill now heads across the Capitol, where it faces a less-receptive audience. The Senate spent eight hours debating the bathroom bill Tuesday — a proposal that's seen everything from tear-filled testimony to fiery protests at the Capitol this year — eventually approving it on a 21-10 vote. The bill would regulate bathrooms in public schools and government buildings, based on the sex listed on a person's birth certificate or other forms of state-issued identification. The latter was a provision author state Sen. Lois Kolkhorst added to the legislation on the floor, and while the expansion would help transgender adults who can't switch their birth certificates, it likely wouldn't do much for transgender children who want to use school restrooms that match their gender identity. As senators verbally sparred on the floor, public and law enforcement officials held a press conference against the bill".  
What you need think about
That this is the 21st century and how is this "law", if enacted, going to be enforced?  Are we going to mandate that kids carry their birth certificates to school on a certain day and those kids who are transgendered will wear an arm band for the rest of the year denoting what  bathroom or locker room they can use?  Is that how it will work? Then, what comes next?
