One thing that is true is that all people matter. If we are honest, we don't always act like we believe that. Nor do we treat people like that is a truth. Sometimes, we assume we are better than other people, which is not true. We are different, but not better. Sometimes we assume other people are better than us. Also not true. Others might be better at some things, but that doesn't make them better people. And it doesn't make them matter more. All people matter. Period. Inarguable truth.
Another true and honest fact is that sometimes humans make mistakes. Sometimes people are wrong. Sometimes I am wrong. Sometimes you are wrong. That's the truth. We tend to not make allowances for that. We can be way too hard on others and way too hard on ourselves. I think that fosters a fear of being wrong, and people lie in order to save face. It's not a safe society in which to make a mistake. It's not easy to live out that truth.
It is also true that we need community. We need other people in our lives. But we have become conditioned to staying behind closed doors and windows. We tell ourselves it is enough to concern ourselves only with our families, co-workers, and maybe some friends - and we have convinced ourselves what happens to the rest of the people around us does not affect our lives. Not true. What happens to other people in this society affects our lives, even if we pretend it doesn't. When people are isolated or bullied or hurting or lonely, they can be driven to do crazy things to themselves or others. And every time we ignore our community, we erode our society a little bit more.
And that's the last thing this society needs.
