The Texas border was porous. Legal immigrants and Illegals were coming in at impossible numbers. Most of the State had more immigrants than native inhabitants. The business owners encouraged the immigration because the immigrants were willing to do work the natives would not. Some of the immigrants opened small businesses.
They came to Texas with the understanding they would melt into the local customs and language. Soon, as their numbers increased, the immigrants insisted that their native language be used. The State became bi-lingual. They complained the courts were unfair, so translators were provided.
Soon the immigrants became fed up, they had their own culture and traditions, they wanted to celebrate their own holidays in their own ways. The Government tried to crack down, close the borders, but it was too late.
The immigrants feared their freedoms would be taken away, they formed militias, raided an armory. The Government sent a squad of troops to get back the guns. The Government troops were ambushed outside of town. Civil War was imminent.
The colonists/immigrants declared their independence, forsaking the agreements made with the Government when they crossed the border. The Government sent an army to restore order. The immigrants, now insurgents, holed up in an old church. The army general pleaded with them to surrender. They told him to go to hell.
The general sent in his superior troops, the insurgents were wiped out to a man.
You may say this could never happen. It is said history is written by the victor. The General was himself defeated by the insurgents a month later. You may have figured it out. Texas was born. The church was the Alamo. The rest is true.
When it comes to immigration, maybe we should study our own history, lest it is repeated.
