I think when it comes down to it, morality is measured by the interaction of society and how it moves forward. An ideal society is one where people have the freedom to act, but simply choose not to engage in destructive behaviors.
Rather simple, focus on what is similar, not what is different. There is one thing that makes us different and divides us, but a lot more things that unite us. I struggle to understand why we have to hyperfocus on things that divide us instead of working with things that unite us. This approach, focus on divide, looks awfully similar to other movement that no one really liked.
