Sounds like you're pretty upset about the idea that switching documentation to gender-neutral language is a good change.

(What do hobbies have to do with this?)

You are spending far too much time online if three neutral words sound like being "pretty upset" to you. There's grass to be touched outside. No one really cares.

You should find a better hobby than getting offended because people that have a different world view than yours. Part of growing up is learning to deal with this fact.
