“Many” is not a stretch. Nationwide polls consistently find upwards of a quarter of the population supporting secession of their state. (That’s about the same percentage os households that own a cat.) In the Southwest, it’s a third. Hispanic people in particular are relatively strong supporters of secession: https://mises.org/power-market/reuters-poll-shows-hispanics-.... (In the Southwest, opposition to secession among hispanics only slightly outweighs supports.)

Yeah, many of us do. TX isn’t just a state, it’s a state of mind, and also a former independent state. Besides, if TX secedes, how is Trump supposed to build his border wall?

Around Texas?

> and also a former independent state

All of America used to be independent. Especially Hawaii and Alaska. Should they secede?

If it meant they improved their prospects for economics, culture, etc. then sure, but it wouldn't. And currently it wouldn't for Texas. But if at some point people thought it would be a better deal to be independent for economic or ideological reasons, why should violence determine whether they stay? Might as well just put it to a vote. Britain has got that right, they have let their former colonies leave (mostly) peacefully. And in the case of Scotland, they have even stronger historical ties and integration than a lot of US states, but it was actually put to a vote.
