While I wholly agree with the merits of ending the playing of the national anthem at sorting events (and school Christmas concerts, for that matter), it remains incumbent upon us all as citizens to stand and rise for the anthem when it IS played.  Out of respect.

As an athiest, I would much prefer religion be removed from Remembrance Day ceremonies, school Christmas concerts (again), and for saying grace at wedding receptions.  But as long as they continue to happen at these venues, I will bow my head with the others.  Out of respect.

I have no respect for those who are disrespectful.  (And yes, that includes Trump, but it also includes Kaepernick).
