I let my childrens learn basic karate and self defense so anytime they need skills I told them not to hesitate to make some moves .
But I make sure they will have a maximum tolerance before doing some actions
Trust me there is still bullying in schools today - even with smart phones and the internet.
Best thing to do is get your child involved in being able to defend themself if danger arises.
You can never be to sure these days with all these crazy kids bringing semis to school
Self defense is pointless when everyone in America has guns. Guns will always trump physical strength.
