R. Shalom Carmy, “Orthodox Judaism and the Liberal Arts” in Academe, Jan-Feb 2001 (link):
In the 1980s a militant politician from Israel visited the United States to hawk his wares. Years later, this man was banned from candidacy for the Israeli Knesset because his anti-Arab harangues violated Israel’s antiracism law (which had been passed with him in mind). Already, the Rav regarded this man’s selective citation of Jewish sources as a distortion and desecration of Torah. He told people close to him that the individual should not be given a platform. But certain students desired the controversial speaker’s presence in our midst. Some, when they learned of the Rav’s displeasure, proceeded to cast aspersions on his Zionism. He, for his part, was not disposed to impose his opinion. The charismatic speaker made his way through the civilized but unambiguous demonstration that greeted him, ascended the rostrum, and allowed himself remarks about the Rav’s religious authenticity that would probably have provoked violence in a conventional yeshiva.
