Bullying in schools

I am just appalled at the level of bullying in the schools these days. When they have to start a movement to help stop bullying nationwide, you know that there is a serious problem. My kids have had to deal with it on occasion, but I gave them permission to fight back against it with multiple different ways to do so. Words can hurt, but I have told my kids that they can combat it with either laughing and walking away or they can turn around and blast the kid. Should they be physically attacked, they have been told that they may defend themselves and to hell with the schools zero tolerance policy. Every human being has the right to defend themselves against physical attack and my kids  will be no exception. If they suspend my kid for defending himself/herself, I will take my children on vacation to Disney as a reward for standing up for themselves.
