Do your research before overreacting. A LOT of Texans actually did immigrate illegally AFTER Mexico declared the border closed and that no more immigrants were to come in. Mexico failed to ENFORCE that edict (much like we have failed for YEARS to enforce our immigration laws). Yes, a lot of Texans were illegal immigrants. That is a fact of history that can not be overlooked.
Now, if Mexico wants it back, then Mexico must take back its illegals here and then fight for it. We fought for it and WON.
“A LOT of Texans actually did immigrate illegally AFTER Mexico declared the border closed and that no more immigrants were to come in.”
Since you consider “woah” to be an overreaction, I hesitate to ask if you have any sources for that claim, or an approximate number to put with “a lot.”
