There are a lot of "lurkers" here that don't comment, participate, however you want to say it.
Also disagreements, hurt feelings, rarely get let go of. They become banned never to be revisited IE forever, or just leave.

We seem to be better at shooting ourselves in the foot.
Sometimes we read things the wrong way and see a insult where it wasn't intended.
I have no room to talk on this as I have been guilty of it myself.
