They
do have rights, the basic human rights that attach to humanity. They
don't have the specific privileges and protections of citizens. That includes:
- a lot of due process stuff that our Founders invented out of anger for what the British had done
- exercising sovereign power (voting, sitting as a juror, protesting or petitioning government, etc)
- accessing welfare or government services tied to an individual level (schools or hospital slots), although they get access to things open to the general public (parks, waterways, etc)
- driver's licenses, since driving a motor vehicle is a privilege. (freedom of movement is a fundamental human right but states have a strong interest in limiting or regulating it)
- any other benefit a government provides to its citizens, which is way more a part of your life than many realize
So you can arrest, deport, and restrict illegals in a number of ways citizens would never accept from their government. You can't indiscriminately kill, imprison, torture, enslave, or otherwise dehumanize them.
The big lie the left has claimed, the massive Overton window shift that the right has yet to fully push back, is that international concepts like asylum, refugee relief, and migration are part of those basic human rights. They aren't. They're legal constructs attempting to formalize and facilitate the movement of humans that happen every day of recorded human history, and have the potential to destabilize the countries debating these concepts.
