Of course it isn't.
One can have perfectly reasonable and not at all anti-Semitic reasons for believing that Jews have no right to country. Or that they should all be exterminated. Who is to say that's anti-Semitic? Certainly not J Street U, which like every anti-Israel group, thinks that the "Anti-Semitism Awareness Act” is dangerous and unhelpful.
The president of the student group J Street U has argued that it is “unfair” to describe all those who seek to end Israel’s existence as antisemitic.
Zoe Goldblum’s comments were sent last week “on behalf of the leadership of J Street U” to the House Judiciary Committee, as it held a hearing on antisemitism on US college campuses.
"Applying the label of ‘anti-Semite’ to all those who oppose the existence of the State of Israel is unfair and unhelpful overreach that ignores the nuances and sensitivities of a complicated political debate,” she argued.
It's nuanced.
"Dangerously, it sends a message to students that free and open intellectual debate is somehow at odds with support for Israel."
Now, mind you, J Street U doesn't have quite this position for a students who might call for deporting all black people to Africa. But the destruction of Israel? Well that requires nuanced debate. And censoring J Street U's anti-Israel allies would violate that open and free intellectual debate. The one that the left is only willing to extend to causes and agendas that it supports.
