Response to player protests

[Scrapper1]

With all of the attention on player protests during the national anthem recently, have you ever had to deal with this at a game? What would you do, if anything, if a player (or team) took a knee during the anthem?

This happened in my area last season and the school stopped playing the anthem before games.

I've had officials tell me that if a team took a knee, they would refuse to officiate the game and leave the venue.

So, has this happened in one of your games? What would/did you do in such a situation?
