institutionalized bigotries

This would be an example of institutional antisemitism. Facebook isn't staffed by Holocaust deniers, certainly, but their responses to Denial go beyond inadequate.

Btw, I checked Newsvine. They seem to have instituted a policy that to accuse anyone of being antisemitic or Islamophobic is against their terms of service. As for actual antisemitism or Islamophobia, I'm sure it's still allowed.

Are you now, or have you ever been Jewish? (I mean Zionist, of course.)

Malcolm Hoenlein has been telling everyone who will listen that something dangerous is happening among the American elite. A short version of his view holds that pro-Israel positions among American Jews are being delegitimized by being defined as "anti-American."

Of course, even if most Americans disagree, it is hardly un-American to hold an unpopular political opinion in America. In fact, protection for unpopular, political views is (theoretically) enshrined in our most basic values.

Yet it happens to be that most Americans happen to hold pro-Israel views. So what does it mean when the views of Jews are seen as illigitate even as they coincide with the views of most Americans? It is the Jewishness of those Jews holding such opinions that is being attacked.

Via Orthodox Anarchist, who also expresses concern about the rumors about Dennis Kucinich and AIPAC:

Before the rumor started circulating that Kucinich threw AIPAC out of his office, his Congressional campaign had no cash on hand. The following week, after the rumor had burned through the web leaving a trail of anti-Jewish outpourings in its wake, he had $4 million.

Among people donating to Kucinich, of course, there's likely to be a repudiation of all Americans holding pro-Israel views. But are most Americans getting called un-American for it?
