How offensive is this policy? You can be disrespectful to the American national anthem by objecting to it by sitting down and yet this is considered the solution. Nonparticipating students have to be cautioned against disruptive activity during the national anthem.
The policy allows disrespect during the National Anthem and an issue only arose when some students refused to stand up for the optional "African-American National Anthem," whatever that could be since African-American is not a nation but an ethnic group. The school is bending over backwards to be politically correct.
