Would you have handled this differently?

Seems like an overreaction to me. Granted, she's a stupid bitch, but stupid bitches can believe and say what they like outside of class. If you had heard her say this in the grocery store, would you still expect an apology?

Also, a forced apology isn't an apology...so what does your line accomplish, exactly? Though it's probably best your assignments get graded by someone else now, that's the only good I see from this.
