I forgot to mention two other things:

1. This applies to sexual and gender orientation as well as race. By seeing each other as children of God we recognize that nobody except Jesus is perfect, and we are all sinners. While we may disagree with the relationship or gender identity of others, that is between them, their partner, and God. It’s one thing to not support something you don’t believe in, it’s another thing to harass someone for a difference in beliefs. I personally believe that marriage is mandated by God to be between a man and a woman and that homosexual marriage is a sin. But guess what? I’m a sinner too! God loves all of his children, no matter what age, race, gender, sexual orientation, or whatever they’ve done in their past. He loves all of his children, and we should too. I have plenty of friends of various sexual and gender orientations, and we respect each other’s standards.
2. Stereotypes are a generalization of schemas, another theory in psychology describing how we process information about the world around us and make knowledge claims. Analyzing every single bit of information is incredibly time-consuming and would make it impossible for us to function. Instead, we form schemas, which are little pigeonhole groups that we classify information into. A very good example of this is music. For example, I listen to EDM. I can listen to a song and tell you if it is glitch hop, dubstep, progressive house, electro house, bass house, drum & bass, drumstep, hardcore, hardstyle, neurofunk, big room house, mainroom house… it’s a very long list. But four years ago, EDM was all just “dubstep” to me. I had to expose myself to EDM until I started to see the differences and could form more schemas than just “EDM”. I believe this is the cure for stereotypes: exposure. I have no proposals on how to do this, but I believe that if people interacted with people from a myriad of backgrounds, they would be less likely to form stereotypes about them or existing ones could be broken down.
