Anti-Defamation League's head Jonathan Greenblatt has a strong reaction to Trump's Muslim ban:
"If one day Muslim Americans will be forced to register their identities, then that is the day that this proud Jew will register as a Muslim," Greenblatt said.
The Trumpites are lying, of course, when denying "that he had ever advocated establishing a registry for monitoring people based on their faith." As the Guardian notes:
...in a video shot at a campaign event in Iowa in November last year, Trump said he would certainly implement a database for tracking Muslims, and that Muslims would be legally obliged to sign up.
I've been declaring for years that I will join Muslims when they're in danger, and this is one of those times.
This ban must be not allowed to stand.
