On some level, this is about defining Donald Trump. Some want to define him as racist, xenophobic, against all religions except Christianity, etc. Trump himself has always claimed he is not. If Trump really was, I think he'd let you know it. The fact that he works with Muslim and Jewish leaders overseas is more consistent with Trump's claims than his accusers.
The Supreme Court ruling may not be the end of this issue. The Appeals court overturned the Hawaii court's prohibition against the government reviewing and updating the Visa program. If the Visa program is now revised with new rules, will Chin file another lawsuit halting the revisions? That would depend on what the revisions are, and what the Supreme Court rules on.
