There are a lot of busybodies on Github, sometimes these go viral on Twitter and other locations for the heated discussions. Here's a small collection of various levels of offence. Some are merely polite requests and some are "horribly offended". I think one or two of them may even be concern trolls but that doesn't matter since they still got the changes made.

There are a few hundred other examples to pull from, these are just a few I chose at random while trying to select ones that are more about the code, or terms used in the code, than contributors or maintainers of the code.
