I agree that all residents of a state should be accorded the same protection under state law and the U.S. Constitution, but here we are talking about granting a specific right to illegal immigrants, and immigration is solely a federal issue and that is my argument.
Now if the U.S. Supreme Court ruled that illegal immigrants have a right to a college education, or if Congress passed a law to that effect, then the matter would be resolved. But in my opinion the individual states don't have the legal authority to pass such a law.
