Now, I don't think it makes any sense that speech is "material" support, but I also think it doesn't make any sense that speech is "violence," and US culture seems to have repudiated my thoughts on what distinguishes speech from action.
But whatever I think, under current law, speech in support of a terrorist organization is no longer free speech. And certain pro-Palestinian organizations were defined by the previous administration to be terrorist organizations back in November. So it follows that certain pro-Gaza activism is no longer free speech. I don't think this should be the case, but this is the current state of the law.
My understanding is a US citizen could promote a terrorist organization like Al Queda and that would not be a crime (if no imminent threat) as it’s protected speech.
They could be investigated, but if no crime is committed the won’t be consequences.
If you’re a green card holder you most certainly could have your green card yanked for the same speech.
Green card holders are still immigrants and liable to be removed from the US for a host of reasons that aren’t actual crimes. Heck, “moral turpitude” is a reason for losing your green card, and that includes a whole host of speech that promotes things like war crimes.
"Material support" is logically defined as more than mere statements of support, and supporters of these groups may advocate for or participate in these organizations.
Specifically it's seems as though an organization was working with terrorist groups to provide training on how to seek non violent solutions with global humanitarian bodies.
Seems like for this to be similar it would require the government to show they individual engaged in direct actions to provide aid to Hamas greater than statements/speech to meet the current definition of "material support".
For statements of support of a terrorist organization to be considered "material support" I think it would require a new ruling from SCOTUS
Croatia gave him a fair trial and found him not guilty. Despite that he can’t ever come back to the U.S.; this situation is analogous to what the protester from Columbia is facing. Basically, USCIS can decide you lied on an application about a crime they think you committed, without actually being convicted of that crime. (Or in the case of Slobodan Mutic, eventually being found not guilty.)
