The current (2019-10-10) version of the network-wide Code of Conduct emphasizes the use of gender-neutral language. This is not expected to be a significant change for Chemistry Stack Exchange since the posts on this site are usually about chemistry and not about people. Nevertheless, we might want to check if there is still anything that can be improved.
This meta post tries to raise awareness that gendered language could be an issue on Chemistry Stack Exchange, too.
This meta post also tries to gather some guidelines about best practices from well-established sources (and does not try to invent our own new rules) – like we did for various other topics. These guidelines are meant to be recommendations, not absolute rules – this meta post is supposed to help you and not to limit you. So please don't start an edit spree just to change some words that you might find in a new style guide if there is nothing else to be improved.
