Don't know what? I'm posting U.S. Code.
This is akin to the free speech argument regarding "shouting fire in a crowded theater." It's not unconstitutional to stop people here on temporary non-immigrant visa from organizing rallies to radicalize people for terrorist organizations.
Are you suggesting that HAMAS has a free-speech right to come to the United States and organize rallies in support of terrorism against Jews?

Define “terrorism against Jews”.
Advocacy for killing, raping, kidnapping, hostage taking, bombings is not protected by the First Amendment, whoever does it.
Advocacy for a change of title over some foreign piece of land is. As far as I can tell, a lot of the “outlawing antisemitism” statutes rely on how speech makes people feel, not on what is being said. I’m not an expert on these laws, I only know what I read, mostly on FR.
There is an unresolved war over possession of territory in former Ottoman Syria. Advocacy for one side or the other to win without incitement to violence is protected speech, whoever is speaking.
