A civics lesson is in order.  Protest is the bedrock of a functioning democracy.  Non-violent protest should provoke and be inconvenient otherwise it's not a protest.

The other option is to eliminate the playing of national anthems at sporting events.  In the case of the NFL it has been used by the US military to stoke jingoism and militarism and, also, enrich NFL owners by paying them millions to advertise their brand.
