“What I’m doing here is maintaining the academic freedom of the teacher,” Hill said. “For me, it’s an issue bigger than this one issue. It’s about the fact that teachers in the district went to college, got a degree and a license to teach.”
So, I guess he is reinterpreting the first amendment as well as the second. “Academic freedom” is not a first amendment right, nor is that right granted through a college education, degree, or a license to teach.
I saw another story on this that notes that the school dropped the “U.S.” from its original name. The U.S. part, of course, is the name of General Ulysses Grant and the school dropped the name to just “Grant” to avoid discussing General Grant. http://www.publiusforum.com/2014/03/24/illinois-school-gun-rights-government-allows/
