Having gone up against several pro se's in the last couple of months in trial courts, I can say for certainty that there are areas of the law that people can for sure make fools of themselves trying to articulate without at least a BASIC legal education. By that, I mean something along the lines of the fairly recent Masters of Legal Studies or even some better paralegal training. Not necessarily law school per se, but SOMETHING more than undergraduate business law or even graduate education law for admins to be.
However with all that said, this case is the opposite. It begs the question of ANY court that hears it and even THINKS of ruling against (in this case) Texas: what part of ILLEGAL do you not get? This case stands for the idiotic proposition that illegal means nothing IF there is a tangible benefit to the (also illegal resident) children.
So does that mean that petty theft, or even bank robbery, is justified if it helps feed your kids? Jacking a car is justified if it means getting your kids to the doctor or hospital? Committing violence is fine if your kids benefit from it?
Hell no. Like too many USSC decisions, this was an engineered decision: the court decided an outcome it wanted, then wrote an "opinion" to get there. That's not their role. In this case, the court pretended that illegals have no educational options in the countries they came here from and that it was our job to educate all kids, regardless of status or criminal activity.
It was a disgusting decision, regardless of how you feel about kids and education, and Reagan SHOULD have said, no, we're not going to enforce this.
