They should have played Dixie for the Hamas Freaks, plus bring out Colonel Reb in full Southern Plantation Owner attire and tell the Hamas Freaks that not one step more or there will be hell to pay.
The other thing I would do is, I’m pretty sure Ole Miss has a Kappa Alpha Fraternity Chapter on their campus, they were known as the Kappa Alpha Order, back when I was at UF in the late 70s they used to have a social event in the spring when the brothers dressed up in Confederate Uniforms and rode horses to the house....trot those guys out for the Hamas Freaks to get a look at. The spiritual founder of the Kappa Alpha Order was Robert E. Lee.
