No it isn't just whatever...it is a specific US Supreme Court decision...so while you may say it specifically does not..it is clearly having that effect since children, including US citizen children are being withdrawn from school in Alabama.
The court majority found that the Texas law was "directed against children, and impose[d] its discriminatory burden on the basis of a legal characteristic over which children can have little control" — namely, the fact of their having been brought illegally into the United States by their parents. The majority also observed that denying the children in question a proper education would likely contribute to "the creation and perpetuation of a subclass of illiterates within our boundaries, surely adding to the problems and costs of unemployment, welfare, and crime." The majority refused to accept that any substantial state interest would be served by discrimination on this basis, and it struck down the Texas law.
Texas officials had argued that illegal immigrants were not "within the jurisdiction" of the state and could thus not claim protections under the Fourteenth Amendment. The court majority rejected this claim, finding instead that "no plausible distinction with respect to Fourteenth Amendment 'jurisdiction' can be drawn between resident aliens whose entry into the United States was lawful, and resident aliens whose entry was unlawful."
Again - SCOTUS WILL have an opportunity to re-visit that issue. I am confident of that.
Alabama legislators took extreme care to ensure that the law was written in a way to pass constitutional muster.
Your
quote DOES NOT address whether or not it is constitutional for schools to check the immigration status of students. It addresses whether or not the State can bar illegal children the right to ATTEND school. The Alabama law, as it is written AND is the law of the land (as of RIGHT NOW); CLEARLY does NOT bar ANY child from attending school.
Many illegals are VOLUNTARILY pulling their kids from school; but it IS NOT because their children are being barred.
So yeah - whatever...
