You all have probably noted that there have been some contentious threads recently, ultimately ending in a few people being given a time-out from posting on these lists.
I don't normally get into things on this list, but it has been generally discouraging to see a bunch of generally nice and reasonable people get sidetracked into unproductive, sarcastic, and unhelpful remarks. There are some efforts underway to formalize what is in and out of bounds - but I would suggest that we are losing our way when we need to get to explicit lists of things not to do.
Unfortunately, we are getting there.
I would like to reemphasize that we are bound together by the things that we share. We love working on Python. We love being in the community and seeing it grow. We can make our community stronger and more pleasant by choosing to emphasize the things that we have in common and by ignoring or avoiding topics that are more likely to generate unproductive discussion.
We can and should also try to remember that not everyone is coming from the same place, and so we should actively assume the best of others and interpret what they say in the most charitable way possible. Think of it as Postel's law  as applied to people.
I'd also suggest that generally, 1) use of profanity, 2) use of sexual terms and imagery, and 3) use of specifically denigrating terms to refer to a person  are completely out of bounds for the professional environment we want to maintain. It is ok to attack arguments, and ideas, but ad hominem arguments - those attack a person, rather than the person's argument - are also inappropriate. Use of sarcasm should be strongly moderated, as it is not correctly interpreted by many people.
No reply is needed to this email. Instead, I'd prefer to see a continuation of solid technical discussion, rather than meta-discussion.
