University presidents testifying before Congress

*US university presidents to testify before Congress over claims of antisemitic protests on campuses.*

Antisemitism is a vicious attitude, just like antimuslimism, racism and sexism. However, the right to express those attitudes is part of freedom of speech.

Many countries other than the US have prohibited expression of those attitudes. Whether that reduces them is not at all clear, but it certainly infringes on freedom of speech.
