I don't understand the issue that someone would have with these words unless they're looking to do something that is prohibited. Is a conservative mindset where they're looking to keep things the way they were? Do they feel that taking the effort to be as inclusive as possible hinders growth? What's the beef?
Of course, the people writing the codes of conduct are speaking for themselves, not the perceived group identity mentioned above, and the poster is attempting to speak on behalf of the group they see, probably without carefully apprehending the range of opinions that exist within the group.
I'd also consider the idea that much of the push back is disingenuous sophistry coming from people that enjoy going to conferences and hassling people.
