> I find it interesting that your way of proving anti-Zionist sentiment is to demonstrate that there are quantifiably more leftist editors on Wikipedia. That does not demonstrate your thesis of anti-Israeli bias. Plenty of people who at least claim to be leftists are profuse in their support of Israel.

It’s not definitive proof of anti-Israel bias - it is, however, evidence. As opposed to the unsubstantiated assertion I responded to.

Evidence of what? A leftward slant in Wikipedia, if you believe the conclusion of these studies (or the summaries of them - I haven’t read them all). And it's easy to see that such a slant would broadly coincide with somewhat less support - though far from zero support - for Israel in 2022 and the past couple decades.

I’m not sure how leftward the slant is. It could be slight. It could also not be relevant in specific areas (such as the Israeli-Palestinian conflict). I didn’t exhaustively research the topic (nor did I believe Wikipedia had any specific leftward slant before today.) If you find anything useful, please share your findings - happy to read!

“Quantifiably more leftist editors on Wikipedia” isn’t a good summary of the headlines of those 5 studies.

To your other point, number of editors matter - and the Israel-antagonists presumably outnumber the Israel-supporters - but it’s far from the only thing that matters. To name a few more things that make an editor more or less influential: the number of edits made, the prominence of their edits (for example if it is in the introduction vs elsewhere in an article), the degree to which the edits are neutral vs slanted, and the relative power they have as editors.
