if you think you will win the perception war by gunning them down or let them starve near the border you are mistaken. All you will get is that the federal government will have the justification to send in the military and remove the texas government. That would either lead to a civilwar or to the same result as having more possible democrat voters in texas.

Just flood their cities with the people they alleddgly champion and want to protect. And see public opinion change pretty fast and get these people removed from office without too much bloodshed. And I doubt its feasible to send that many back where they came from with planes or buses if they can try again to come back.
