Interactive time

It’s time to get interactive here, people:

For two points: Tell me a deeply ingrained belief you hold, about which you think you might be wrong. I’m not talking about those idiots over there, those ones that we always make fun of. I’m talking about you. You, my beautiful and highly intelligent friend. What are you wrong about? I’m looking for things at the level of “women don’t deserve the vote” and “we can enslave those brown people because they don’t have souls.” What will your descendants cringe to admit that their grandparents believed?

For a single point, you may tell me what I’m wrong about. Please note that a long list doesn’t give lots of points. One point for one mistake, and that same point for many. You will not achieve a second point without picking on yourself.
