It’s hard to have an opinion or an idea about something if you’ve never tried it. Brussels sprouts might not look or smell tasty, but how do you know unless you’ve tried them? Baseball might not seem like it’s fun to play, but until you’ve picked up a bat and taken a swing, it wouldn’t really be fair to call baseball a snooze.
An opinion formed without any real reason or knowledge is known as a prejudice. Usually “prejudice” refers to an unfair opinion about a person or a group of people. Have you ever heard someone say “all girls are bad at sports”? That’s a prejudice! Plenty of girls are good at sports (many are even better than boys!) so a person who believes that all girls are bad at sports is being unfair and prejudiced.
Prejudices take ideas that aren’t true and can’t be proven and act like they are facts. When people base their actions off prejudices, it hurts others. Let’s say someone who owns an ice-cream shop has a prejudice against kids. Maybe this person had a bad experience with one mean kid who stole from him, or maybe he believed someone who told him all kids are troublemakers. Now he has a prejudiced belief that ALL kids cause problems. He doesn’t let any kids come inside his store and turns you away even though you’re polite and well-behaved. It probably wouldn’t feel very good to be treated this way! His belief that all kids are naughty isn’t fair. You deserve to be given a chance and treated like an individual!
