Well, your short stay in Texas 50+ years ago does not qualify you to understand , or have a feel for what Texas experiencing now.
And no, you can't understand the frustration Texas, and the other 3 border states are experiencing now, because you don't live here, and aren't seeing it first hand, from the way it was, to the way it is now.
Secession was about States rights then, and that's what it would be about now. You are now, and have been for many decades, in your on little world, and know nuthin about anything outside it, other than what you read, or see on TV.
You know nuthin about our economy, our culture, economic potential or weaknesses, and have no knowledge of what we could, or couldn't accomplish if freed from the burden politically, and economically from the liberal north.
Your advice, and prospective on Texas and its issues are as constructive as our present Washington government.
