What will you tell when I ask you about "your group"?
And what will you tell when I ask you about "their group"?
Most people will say only the good about themselves and bad about the others.
But.. Have you ever think how it can possibly happen? And why do people usually think positively about themselves but negatively about others??

Stereotype is one's idea about someone because of they belong to one group. It can be harmful when the people are too fanatical to their group.
What can we do to get rid or it?
It's true that we're all different. But differences make perfect! We have to put in our mind that everyone's just the same! All of us have the same rights, to do what we wanna do, and also to be loved. Here's one thing that I learn from a song lyric: "It don't matter if you're black, white or yellow, if your brown or red. Let's get down to that, love is color-blind. You're my brother, you're my friend, all that matters in the very end is to understand love is color-blind"
See? We have to understand that the right way to see people is not from their physical appearance. We have to see their behavior to understand what they are really like. Never judge a book by it's cover!

"in all things, to all colors, always be kind!"
