There are close to 13 million LEGAL IMMIGRANTS from Mexico in the US. You can’t deport them. And the total Hispanic population is now 51 million in the US.
You can assimilate them and make them learn English if the invasion is stopped and reversed. In addition to that, the ones here on work Visas or overstaying their legal stays here can be sent home. Add to that, if they commit crimes, can't they have their immigrant status revoked?
No, but you can make English America's official language, end "bilingual" (Spanish only in reality) programs in schools, stop sponsoring "Chicano studies" programs at State Universities that promote the La Raza mindset, and make it more difficult for those here legally to bring their extended families over. If you do this, those that want to assimilate will stay, the others may be motivated to self-deport.
Deport them all. Legal, illegal, Hispanic, Asian, everyone. Then build a 25 foot titanium wall.
