How deal with racism?

People of this nasty and uneducated nature do not deserve the time of day. To respond is to please her. Avoid her at all costs unless she becomes physical. Then you will have to take action and report her. She does this to make herself feel superior. Funny thing is that she does not even realize that she is just a stupid immature bully regardless what she says or her personal prejudice views. Sorry you have to go through this. People can be terribly brutal no matter what color their skin is. Just ignore her without a chip on your shoulder and without a snobbish or sheepish reaction. You don't want to give her more reasons for her to taunt you.
