As a result of the internalized or unchecked antisemitism of the majority of its editors (just like the majority of people in the offline world), Wikipedia has taken on a decisively antisemitic slant. Thus, a toxic environment is created wherein anti-Zionist narratives and editors are privileged over neutral or pro-Israel ones. All they need to do is gang up on the other side, proclaim them “biased”, “single purpose accounts”, “POV pushers”, etc, and then wield numerical sway to effectively silence the opposition. It is an antisemitic mob’s wet dream.
Israel-related articles almost uniformly emphasize the Palestinian and Arab narrative while marginalizing the Jewish one. Rudimentary facts about Israel’s history: including Palestinian massacres on Jewish civilians, Arab intransigence being a primary factor in the conflict’s intractability, and even the Jewish people’s origins and indigeneity to the land of Israel are either downplayed or outright erased. On some articles, it fails to recognize Jews as an ethnic group in the Middle East, whereas others engage in casuistry in order to present anti-Israel opinion as incontestable fact.
...So what can be done about this? The answer is simple: everybody who cares about the truth must create an account, learn the site’s rules, and push back vigorously against those who would defame or delegitimize the Jewish people on the world’s largest online encyclopedia. Do not be intimidated by the task at hand, for there is too much at stake. If all else fails, we must pressure Wikipedia itself to remedy this problem, or face a community wide boycott. Unless we do something, antisemitism will further metastasize to a point where we will no longer be able to fight it.Source
The remark about "the Jewish people’s origins and indigeneity to the land of Israel" presumably refers to the point made in Shlomo Sand's book "The Invention of the Jewish People" that widespread conversion to Judaism over the ages means that many people who calls themselves Jews today are not descendants of the ancient population of Judea. Sand argued that the dominant ethnic group in Israel, the Ashkenazis, were descended from a Turkic people called the Khazars who converted to Judaism around the 8th century. This, at the very least, is a serious scholarly debate. But it seems the Jews want to brand it "antisemitism" and shut it down.
The author suggests three strategies, including fallback options:
1) Jews should infiltrate Wikipedia and use it to propound pro-Jew points of view.
2) If the goy successfully resist this infiltration, go over their heads and complain to the management, asking them for some kind of special intervention that suppresses ordinary democratic procedures.
3) If this is refused, shun and discredit Wikipedia as a source of information.
Or to put it another way: TGKSID.
