In my opinion, standing and kneeling during national anthem are both acceptable.  Kneeling has been done for centuries, showing respect for the dead at funerals, etc . . .  As a US Navy, Vietnam combat veteran, my loyalties are to the flag and anthem, but I respect people's freedom of expression, their rights that I fought for.  My issue is in the venue they choose to air their grievance and social issues.  Why not do it via community involvement where your efforts could make more of a change and enlighten others.
