I live in Texas and there isn't a lot we can do other than calling our congressmen/senators. Our politicians (Texas and US) refuse to support or deal with the issue. Not only do they not support law enforcement that actually penalize them for taking action (ACLU).
One thing to note is that the Alamo didn't turn out well for future Texans. It is what we remember but San Jacinto is where we took ownership of the big state.
Also my wife and in laws are all Mexican immigrants (3-4 generations legally here in American). They find this issue to be embarrassing for the US. I never see anything that supports Mexico on them, near them or flying. Their family left that country because of corruption, poverty and the inability to pursue a good life/happiness.
At one point in time the Native Americans were the inhabitants of America (whatever they called it then). However after an influx of immigrants, introduction of policy, laws and their inability to stand together to beat back the influx, they forfeited their rights and sovereignty. I wonder what the Mexican immigrants are going to call their new country after we stand around idle and let them have it?
