"Trump supporters have a remarkable ability to coalesce around whatever explanation they are told to repeat, so the arguments defending the detention are likely to orient around this justification. The idea that Khalil’s views might have “serious adverse foreign policy consequences” for the United States is an obvious pretext for expelling him—and a message to others who might hold or express similar beliefs. Trumpists simply do not approve of his politics and have therefore resorted to using the power of the state to deport him. Trump has styled himself a champion of free speech, but this is what Trumpists mean by “free speech”: You can say what Trumpists want you to say or you can be punished.
Trump has announced as much, declaring that the administration would not tolerate “pro-terrorist, anti-Semitic, anti-American activity.” That is an admission that Khalil’s arrest is not about consequences for American foreign policy but about punishing speech

Due process is a cornerstone of democracy and the rule of law. Without it, anyone can be arbitrarily deprived of life or liberty. Leaders who aspire to absolute power always begin by demonizing groups that lack the political power to resist, and that might be awkward for the political opposition to defend. They say someone is a criminal, and they dare you to defend the rights of criminals. They say someone is a deviant, and they dare you to defend the rights of deviants. They call someone a terrorist, and they dare you to defend the rights of terrorists. And if you believe none of these apply to you, another category might be “traitor,” the label that Trump and his advisers, including the far-right billionaire Elon Musk, like to give to anyone who opposes them."
