Agree or disagree with the policy proposal, that is not what Trump has been saying at all. I don't know if this is an unforced error with some people in the discussion of American politics or a deliberate attempt to muddy the waters. There is a legal process for immigrating to the United States, it is a significantly easier process than that which exists in the majority of Western countries.
Those who follow the legal process are not being targeted by any policy proposal that's been espoused by any mainstream political candidate from any party in the United States, the issue has been and continues to be discussed only in the terms of people who immigrated to the United States illegally either via violating the terms of their visa, fraudulently receiving a visa, or crossing the border without a visa.
Please tone down your hyperbole.
