We have two options. One is to censor and hide information. The second is to learn to be more tolerant and just accept everybody makes mistakes and says stupid things at times. If you're religious, you can't hide stuff from your god. If you're not religious your only judgement is by others and perhaps you deserve it.
With the internet what is unfair is how by and large people were fooled into thinking they were anonymous, I think allowing that belief and taking it away without peoples knowledge is a form of entrapment (or perhaps not educating the populace on the consequences of actions when they were always there). While anonymous people say things for reaction that they do not necessarily believe or mean. Perhaps that is a mark on their character. I was taught to believe that sticks and stones may break my bones but names will never hurt me. This goes in two directions.
We are each individuals who have our own path to forge. I pity those who try to control others. I pity those who act without thinking. Don't live in the past, the key is to move on and learn from your mistakes, better yet learn from others. That is wisdom. Hakuna matata.
