A definition of antisemitism has been adopted in numerous laws that criminalize speech that abridges that definition. What First Amendment? From Chris Hedges at chrishedges.substack.com:
Those who testified at the state capital against New Jersey’s adoption of the IHRA, arguing that it would criminalize free speech, had our microphones muted and were shouted down, proving our point.

The Final, Final Solution – by Mr. Fish
I testified at the New Jersey state capital in Trenton last week against Bill A3558, which would adopt the International Holocaust Remembrance Alliance (IHRA) definition of antisemitism, which conflates anti-Zionism with antisemitism.
“This is a dangerous assault on free speech by seeking to criminalize legitimate criticism of Israeli policies,” I said. “The Trump administration’s campaign to ostensibly root out antisemitism on college campuses is clearly a trope to shut down free speech and deport non-citizens, even if they are here legally. This bill falsely conflates ethnicity with a political state. And let’s be clear, the brunt of repression on college campuses is directed against students and faculty who oppose the genocide in Gaza, 3,000 of whom were arrested and hundreds of whom were censored, suspended or expelled. Many of these students are Jewish. What about their rights? What about their constitutional protections?”
“I have had numerous relationships with Israeli journalists and political leaders,” I went on. “I knew, for example, former Israeli prime minister Yitzhak Rabin who negotiated the Oslo peace agreement. Rabin was assassinated in 1995 by an Israeli ultranationalist who opposed the peace accord. Rabin stated bluntly on numerous occasions that the occupation was harmful to Israel. Israeli colleagues frequently criticize Israeli policies in the Israeli press in language that would be defined as antisemitic by this bill.”
