So I just looked at issue #7986 on the github. About changing slave to puppet. I do not like this idea of political correctness being invaded into Godot. Master/Slave is the standard. The idea that the keyword slave would effect some one is ridiculous. There is no need to change the keyword outside of pleasing pipsqueaks that are "more holier than thou".
I'm okay with it being an optional word, but I know that's no going to last. I would advise not giving into this crowd. As we risk dividing our group into a matter of left-right politics. Can you imagine some one forking the project, entirely for political purposes?
