In a recent post ( How to fight back against antisemitism ) I suggested that we can all fight back against the blatant antisemitism and Jew hatred that has exploded in our communities following Hamas's terrorist attack on Israel. My suggestion was to expose the names of those who put their names to petitions calling for protests against Israel/Jews.
AIM, Accuracy in Media, has done much, much better. Following the many antisemitic rallies, marches and petitions against Israel and Jews in Universities in the US, AIM has set up a series of campaigns to draw attention to antisemitism and to expose the anti-Semites. The mobile billboards on a truck display and shame the leaders of the antisemitic rallies. These have gained results with students losing scholarships and no doubt some will have trouble gaining employment.
Here is one of the videos; there are many more on the site
As a result of seeing the exposure of their colleagues perhaps some will tone down their rhetoric Or perhaps not. In any case, it proves the point. You can and should have free speech, but you cannot have it anonymously. If you believe strongly protest, speak up, but give your name. Then others will decide whether they believe you have the right character for their scholarship or job.
