A genuine answer, how about looking up some studies on this subject? Not those done by Wikipedia of course, they claim to be politically neutral after all.
Six studies, including two from Harvard researchers, have found a left-wing bias at Wikipedia:
A 2024 analysis [1] by researcher David Rozado that used AllSides Media Bias Ratings [2] found Wikipedia associates right-of-center public figures with more negative sentiment than left-wing figures, and tends to associate left-leaning news organizations with more positive sentiment than right-leaning ones.
A Harvard study [3] found Wikipedia articles are more left-wing than Encyclopedia Britannica.
Another paper [4] from the same Harvard researchers found left-wing editors are more active and partisan on the site.
A 2018 analysis [5] found top-cited news outlets on Wikipedia are mainly left-wing.
Another analysis [6] using AllSides Media Bias Ratings found that pages on American politicians cite mostly left-wing news outlets.
American academics found [7] conservative editors are 6 times more likely to be sanctioned in Wikipedia policy enforcement.
There are far more sources out there.
If I show examples of biased pages - the one on Antifa is a good example - this will just devolve into a quibble about this or that sentence.
