One need not think this is good, just, or even lawful behavior by the FBI director, nor think this is in any way comparable to the behavior of Democratic administrations, to think it's irresponsible to advise people to "get travel visas while you still can."
I think it is reasonable to be prepared and have options to leave when basic civil rights and rule of law are being systematically tested and weakened on behalf of the most powerful individual in the country, who had sworn to uphold them. I would say it is irresponsible to ignore or minimize the magnitude of changes in the US in the past 100 days.
I didn't say to sell all belongings and move. I said to have a way out if it becomes necessary. The FBI is being weaponized against judges, right now, and this without any modern precedent.
