Let us begin by saying that it is not fun for any Kid / Child to be bullied at the school.
The emotional damage can drastically change their personality and even scar them for life.
Out of experience i know that i struggled to forgive and let go of the pain from being bullied.
Doing Martial Arts first increases self image, the way the child sees himself / herself.
Once the Kid / Child feels better regarding their image the need to fight goes away.
With a better image they also feel more willingly to defend themselves when the time arises to do so,
instead of just being beaten up.
So this is why it is important to learn self defence against bullies.
