communities, the united states of america, and the anthem repesent "some" people they don't represent all the people.
actions speak louder than words. the flag has changed forms, the national anthem was created by a human, the united states is only as strong as it's people. to serve doesn't mean serving only those that look like us, believe like us, have the same socio-economic status like us.
communities don't have to agree on everything, true.
if jerking a flag up and down a pole rocks someone's world while singing songs of joy, more power to them. but a flag and a lullaby won't alleviate the suffering of those who are being wronged.
so if someone is interested more in jerking a rag up and down a pole knowing that people it represents are being wronged and continue to do so, they've lost sight of the idea even if they still got their eye on a flag.
we the people aren't we the privileged, those who take we the privileged are stroking their egos up and down on a pole.
Lets try this you have a Family You, Your wife and 6 kids all old enough to drive. You have only two cars. Your wife goes shopping with one and without asking your son takes the other. You had a doctors appointment and now you are going to be late. Do you have the right to be mad at your son. Will all father's be mad at there son. Should your wife take your side. Will your wife take your side.
You are all part of the same family there shouldn't be any discourse. The car is not even a symbol of the family it is just a tool. You may not get mad, but some families will. You wife may support you but some wives won't. All this could have been resolved if your son thought of the family first and asked before taking.
Communities are far more varied then families and as such have far more differing opinions on things and while we are a democracy and we can do a lot of things, if the majority of the community thinks what you did is wrong you will have a tough road ahead. If it is something trivial you are being stupid, especially if you have many other options.
A rich football player with 24 hour media coverage and millions of dollars to give away had many other options. It was not even a successful protest until Donald Trump got involved.
