"How would you define a stereotype?"
I think it's a form to divide the society and propagate the hate. It's not a good thing to believe in.

"Which stereotypes do you know?"
The stereotypes of gender, music style, types of clothes and others.

"Do you think it is a problem to believe stereotypes? Why?"
I believe that it's a big problem, 'cause that labels people, putting them against each other and making them believe that some kind of peoples are more important than other.
