you expect them to recall some analogous example of politic deportations years ago?

and anyway, almost certainly the answer is yes; it is not hard to believe that a person's stance is that systematically deporting people for disagreeing with the government is wrong. "Trump bad" is very often on the basis of principles which trump is violating, not just because it's Trump. Surely you realize that people are mad at him a lot because of the thing he does?
