Apex fallacy what is it? Wiki page deleted

Apex fallacy according to Urban Dictionary is a logical fallacy that assumes properties of the most visible/elite members of a group are held by all members of the group.

eg The most powerful people in the World are men, hence all men are powerful. This is an Apex fallacy, not all men are powerful.

eg The World's best long distance runners come from Africa, hence all Africans are good long distance runners. This is an Apex fallacy, not all Africans are good long distance runners.

Apex fallacy seems to be a subtype of Composition Fallacy. Unfortunately the Wikipedia page was deleted by feminist factions claiming it is a neoligism created by Men's right activists to counter feminist ideas of misogyny.

Do people think Apex fallacy has enough legitimacy to be worthy of it's own entry? Or be listed as another name for the composition fallacy?
