Nice try tdub:
"After the 8-1 Minersville decision, in which Justice Harlan Fiske Stone was the sole dissenter, states had the authority to force children to participate in the Pledge. The Court maintained for only three years that ?national cohesion? was of higher interest than one?s personal beliefs.
In West Virginia v. Barnette, the Court's Minersville decision was overruled. Justice Robert Jackson wrote the 6-3 majority opinion, with Frankfurter now in dissent.
Jackson emphasizes that free expression overrides the goal of national unity. A compulsory flag pledge goes against the fundamental values of the First Amendment, which protects freedom of expression and thought from
government intrusion in all but the most extreme cases. He concludes his opinion with a stirring reflection on the dangers of forced ?unity? and the importance of individual liberty."
The NFL is not part of the government, it can therefore require participation as a condition of employment. The NFL hasn't done so.
