A few thoughts.
1) Does this have anything to do with Retirement? Financial Independence? Or reaching FIRE? Is it posted just to be incindiary?
2) I clicked through to the blog post. It includes a scribd embedded copy of an alleged Princeton University HR policy and/or memo. There is NO sourcing to show if this is legit or made up out of whole cloth.
3) If it is a policy memo - it actually makes sense since it is in the context of how to word JOB POSTINGS in a way that is non-discriminatory. But you would not know that unless you a) clicked through to Tyler Durden's blog post and then - actually read the memo/policy paper included in the scribd embedded object.
I don't see anything controversial with suggesting that job titles in postings/advertising try to include both genders.
From the first paragraph of the embedded memo:
Consistent with style guidelines issued by Princeton’s Office of Human Resources and Office of Communications, and as endorsed by the Institutional Equity Planning Group as a preferred University practice, HR has developed these gender inclusive style guidelines, to be utilized by all HR staff members in HR communications, policies, job descriptions, and job postings.
