I'm sure you could find 17 citations that Muhammad had sex with underage girls but that's not the first sentence of the Wikipedia article on Muhammad, is it?
Point being just because something is cited doesn't mean putting it in the first sentence is unbiased.
...what?? What should the first sentence of the Zionism article be if not the definition of Zionism and the goals of Zionists? What would an unbiased but complete introductory sentence look like?
If the foremost notable thing about Muhammad were that he had sex with underage girls, but instead the actual first sentence is about him being the founder of Islam, then you'd have a devastating point here.

The goal of Zionism is to create a safe haven for Jewish refugees, to prevent another situation like the Holocaust where millions of Jewish refugees were murdered.
The issue is that the reality distortion field that is required to maintain the current Zionist narrative is just too strong and it quickly falls apart even just by following some basic rules on fair citation.
Jimmy Wales has no involvement in editing such articles. The Wikipedia Foundation doesn't involve itself in such matters either. For example, when concerns were raised about the ADL (a Jewish NGO) being banned as a source, they responded by (correctly) explaining that "neither the Board or the Foundation make content decisions on Wikipedia. A community of volunteers makes these decisions".
Such content matters are entirely community decisions, so of course a biased community results in biased decisions.
