the last point is tricky cause it involves instilling values into a child.

actually , a kid experiences a lot of things which he would not be able to tackle unless he is guided in a proper way. as a parent you can educate him on bullying who donot necessarily represent any color or religion.

you just need to make sure that your kid doesnot learn from you that color or religion makes you different from the other kid/person, it is just that the other person or kid discriminating him is a bad character.

an old saying "if you feel yourself as loser, then what do you expect others to think of you".....
