For a lot of these people that was not even a given option. They went from having legal status in the US to being on a plane to a foreign prison without any notice or chance to do anything else.
Oh so you're purely arguing in bad faith. They're deporting legal residents by revoking their legal status through dubious means, not communicating said revocation, and then arresting previously legal residents. And "uproot your life or else we'll murder you by feeding you to wildlife" isn't the sort of government service I aim for.
Due process is the process that is due! It's not a court hearing it's a much more simplified process.
If the process to get into the country is next to none, then the process to get out is the same.
