A Code of Conduct hurts more than it helps. So many hours where already wasted with it. Every society has a serval code of conducts and only laws are written down as the fundamental base level. everything else is optional and wil come and go.
Code of conducts can be beneficial, in theory. But most of the times they are excessive and overdone. When I read some of those code of conducts they seem to me to be designed to exclude people and advance some hidden agenda instead of actually helping people. Like the "no hugs" thing recently, or wanting to ban people because they speak with a "tone". Everything is a good excuse to ban other people. I say that the longer the coc, the more unwelcoming the community probably is. Yo! Work on the project, don't be a jerk, if a person says no it's no... That's so simple!
