Pretty much any article on gender claims it's a social construct using citations from "sources" like Mother Jones and fringe extremist social sciences professors. Biology is barely a consideration.

If you look at articles on IQ, the entire page claims any link between IQ and race, which has been repeatedly proven in countless independent studies over decades, is wrong and that all IQ differences are environment, a lie that seems blatantly political.

These pages are locked to anyone except the usual few Wikipedia elites with an agenda.

Particularly this section :P https://en.wikipedia.org/wiki/Category:Propaganda

Conservapedia, while not my choice as a source of truth, has a long list of what they find wrong with Wikipedia https://www.conservapedia.com/Examples_of_Bias_in_Wikipedia

RationalWiki also has a section dedicated to this phenomenon, including multiple points of view: https://rationalwiki.org/wiki/Wikipedia#Bias_in_Wikipedia
