There's nothing they can do about it. Not sure it's worth getting upset about.

I think the players should just ignore it and play. When it looks like something gets under their skin, the opposition will just do it more.

Let the admin or coaches mention it in their opportunities with the press - something along the lines of "we expected a hostile crowd that loves and supports their team, we were disappointed that they resorted to bigoted chants." Leave it at that. Don't get super emotional or upset. Just give the statement and shrug.

Not worth getting overly upset about dumb kids doing dumb things.
