I know that any time you say anything critical of Israel people pop up finding an excuse to scream about antisemitism, but in reality your comment is the one that reeks of antisemitism. Zionism is a political ideology, and I used the term quite deliberately, since I do not know to which extent those involved were Jews (lots of evangelical Zionists too) or Israelis. Since it was CAMERA, an American organization, that was behind the plan, I’d be surprised if all those involved were from Israel. Trying to equal it with antisemitism implies that all Jews and only Jews support Israel, which is in itself an antisemitic trope.
(There have been later plots by settlers to influence Wikipedia, and there “Israeli ultra-nationalists” might be a fitting name)
