Put simply, I don’t believe that the stated purpose is the real purpose.
This is a ban on Muslims under another cover, it has no practical purpose, and that's what makes it malevolent. Like the fact that it was released on Holocaust memorial day, and the statement on that day omitting to mention jews for no discernable reason, it is intended to demonstrate absolute power, and to inculcate a feeling of helplessness in any that oppose the administration or belong to groups they do not respect.
I now believe it is a prelude to much worse. This is why trump has moved from being a political opponent to a moral enemy for many people these last few days.
