You've obviously been reading very different documents than I have about the US justice system. Like the disproportionate number of black people sentenced to death.
There is little evidence that ICE operate a "robust legal system" - https://www.theguardian.com/tv-and-radio/2025/mar/10/john-oliver-immigration-trump
I am sure most people could follow the second point - terrorist and racist extremists operate with the USA and are white US citizens. They operate without let or hindrance. A lot of them voted for Trump.
And support for racist terror organisations by foreign students is not ok. Nobody said it was. And as soon as evidence is produced that shows she did so, they shoud certainly deport her. But no such evidence has been shown. Dawn raids and street kidnappings are the tool of a despotic regime, not a democracy.
