If this question is better for Law, please let me know and I will close it.
I pledge allegiance to the flag of the United States of America, and to the republic for which it stands, one nation under God, indivisible, with liberty and justice for all.
I am not sure if this is still an occurrence, but I remember a trend in those refusing to recite the United States' National Anthem before professional sports games. And it can be seen that students refuse to recite The Pledge of Allegiance.
One could argue that the expectation to pledge yourself to a symbol and entity forgoes one's individualism. On the other side of the argument, forgoing this expectation is a means to label someone un-American or even labeled as treason. I am not sure about in which side I reside.
I would love to hear thoughts on this.
