Employ diabolic tactics. Sweetly assure the child you'd like her to be a Vols fan but she's free make her own choices. Pat her on the head, give her a hug.
In the dead of the night, put on an Alabama jersey, a devil's mask, and carry a stiff rubber pitchfork. Don't forget a small sized flashlight that can actually fit comfortably in your pocket.
Slip silently into her room and sit on a chair close to the door and the light switch. Shine the flashlight below your chin so the mask and jersey are both visible in the dark room In deep but low voice repeat the word "Crimson Tide" until she awakens. When she glances your way, arise say "Crimson Tide" louder.
When she screams, turn the room lights on to temporarily blind her, then off and scoot out the room.
Ditch the mask and jersey in a positioned bag and stuff it into a trash can or some other hidden place. Rush to her room to find out what's the matter. Don't take her story seriously, just laugh but also try to comfort her. Thenceforth, refer to Alabama as the Crimson Devil instead of Tide.
If this doesn't cure her, play Rockytop on player in very, very, very low settings. This creates a subliminal message as she sleeps. Do it nightly for 14 days.
This isn't child abuse, it's non-invasive brain surgery.
