The beginning of a recent Mondoweiss post by its founder himself says:
One of our efforts at this website is to do to Islamophobia what was done to anti-Semitism over the last century: making its expression unacceptable in American mainstream culture. And while I can claim no position of leadership on this issue-- I've had to be educated-- some of our readers are leaders...Weiss goes on to claim that the relative lack of Ramadan food articles in mainstream media is evidence of Islamophobia!
Setting aside that ridiculous claim, in the comments we see:
Expressing antisemitism is quite acceptable in Mondoweiss' conception of mainstream American culture, it appears.
