No, what makes this country great, is that he can do it. Actually doing it does not make the country great. It insults the country.
That seems like overly complicated logic.
Jeebus is absolutely correct the thing that sets our country apart is the fact that it is acceptable, or at least should be acceptable, to protest the government.
It is not complicated at all. What sets our country apart is that it is legal to protest the nation anthem, not that it is acceptable. Of course there are ways to protest the government that are both legal and acceptable. The point, no form of protest needs to be “acceptable”, it just needs to be legal. That is the important thing, and is what sets up apart.
