Immuno blockers suck. My mom has an autoimmune disorder and has been on them for decades to control it. They’re better than not being able to control her disorder of course but every minor bug that goes around is a serious issue for her. Glad this round went well for your family.
It is different because sanctuary rules don’t usurp federal authority. Sanctuary rules prevent state and local authorities from enforcing federal law and cooperating with federal law enforcement for certain crimes which is legal because state and local authorities have no obligation and only a limited ability to enforce federal laws. Texas is claiming jurisdiction in a couple of areas in which jurisdiction is specifically reserved to the federal government, actively interfering with federal agencies, and taking actions that violate federal law and international treaties. Legal passive resistance vs active violent resistance.
