Until now, revocation of a permanent residency Green Card could only occur if its holder had committed a serious felony such as murder or rape, but the empowered pro-Israel partisans of the Trump Administration have now stretched that law to include criticism of Israel or Jews, arguing that such criticism undermined the vital American national goal of combatting antisemitism across the world. When combined with last year’s bipartisan Congressional enactment of the Antisemitism Awareness Act, this might set a legal precedent for actually criminalizing such political views, especially if these can be portrayed as “providing material support” to such officially-designated terrorist organizations as Hamas.
The "deport them all" crowd are being useful idiots for this agenda, unfortunately. While these student visas shouldn't be issued to women in the first place (largely for making anchor babies from the "Mrs. degree"), that's what should be used as the reasoning rather than the third rail of US politics. However, as we all know sensible reasoning will be obstructed at every opportunity and instead the only way to get anything done is because Israel wants it. As such if we get some flavor of authoritarianism out of this, it will be in pursuit of said interests, as the lobby is the only thing capable of suppressing all meaningful opposition to it.
