For those unfamiliar with the term, it's a fallacy used by MRAs to rebut feminist arguments like "all men had the power and oppressed women as a gender", "all men get payed more for their work", "all men are CEOs or politicians", etc:

The apex fallacy refers to judging groups primarily by the success or failure at those at the top rungs (the apex, such as the 1%) of society, rather than collective success of a group. It is when people marginalize data from the poor or middle class and focus on data from the upper class.

Consensus is that this is a non-notable neologism.

Before you go up in arms about feminist censorship, I'd like to point out how the removal wasn't completely unjustified. It had a total of two sources: one legitimate article (+ a republish), and an interview with a psychologist on a site with malware warnings. As far as I'm aware it hasn't been officially used on any other forum besides internet arguments. A couple users cited political bias of sources as a reason to delete, but I'm not familiar enough with wiki policy to comment on whether this was valid reasoning. Some jackass named ZeaLitY was proposing 'Delete' with blatant MRA hate but another user on there told everyone to ignore him.

A good solution to getting the article restored would be if Warren Farrell or another accredited MRA academic found the term interesting enough to publish some information about it.
