Stereotypes

Stereotypes are a kind of generalization that judges a group of people without enough information and limiting them in a wrong perception.
People tend to use stereotypes to stand defects of people out and  generalizing them without the oportunity to correct that opinion.
The problem of this unfounded limitation begins when people are guided only by stereotypes rejecting certain groups without even knowing that these behaviors or facts don't really define each person individually, and this can be reflected in a very bad way into the person who is being judge.
So, before reject a group based on infounded information, think about all positives characteristic instead of bad things and be open to learn more about it!
