The Anne Frank Center — the organization named after the Dutch girl who chronicled the barbarity of the Nazis during World War II — went on a Twitter rage on Friday opposing the idea that “all” lives matter.

“‘All Lives Matter’ is like telling African-Americans to drop dead. It is wrong, and it offends our organization’s values,” the Center “for Mutual Respect” tweeted yesterday.

That wasn’t all. About 30 minutes later, the Center asserted if you really believe “all lives matter,” you should never say “all lives matter.”

“If you really believe all lives matter, you would never substitute All Lives Matter for #BlackLivesMatter,” it tweeted.

An apparent staffer went on to criticize America and Americans.

“A nation that refuses to deal with racism is a nation that mocks its own promise of liberty and justice for all,” it tweeted.

The Center’s anger was likely triggered by the acquittal of Jeronimo Yanez, a St. Paul, Minnesota police officer who shot Philando Castile during a traffic stop in July 2016.

After the verdict, the Center urged Americans to “wake up and smell the pattern of racism.”
