Prejudice prevents you from seeing the world in its entirety. It forces you within some boundaries and it reinforces your perspective by limiting doubts.
When prejudice is taken a step further it becomes righteousness. That’s when you aim at keeping others within the same boundaries built your own prejudice, and you allow them only one possible version of the truth.
Prejudice and righteousness are human traits. That’s why it’s important to remind ourselves of how limiting they are.
