Here's our next owl in our month of learning what we can do about racism. This one is about challenging our own hidden assumptions or prejudices. What kind of things do you assume about people based on their race, maybe without realizing it?
Do you remember the tension between wizards and goblins in Harry's world, which was largely based on misunderstandings and assumptions about each other? Even the friendly Weasleys, who always sympathized with Muggle-borns, still had prejudices against goblins that showed how there was bitterness and mistrust between them for centuries.
Such prejudices can often lead to racism in our Muggle world too. And though they may be hard to get over, being aware of them in yourself is the first step.
