The Black Lives Matter movement has shed light on the racial profiling, police brutality, and racial inequality experienced by the African-American community across America. But apparently some of the employees at Facebook’s notoriously white, bro-centric Menlo Park, California office don’t agree. 
 
 
 
 In a private memo posted on a company announcement page for employees only, Mark Zuckerberg acknowledged that employees have been scratching out “black lives matter” (sic) and writing “all lives matter” on the company’s famous signature wall. The company, whose staff is only 2 percent black, is facing the issue head on.

 “We’ve never had rules around what people can write on our walls,” said Zuckerberg in the post. “We expect everybody to treat each other with respect.” The entire message, obtained by Gizmodo, is posted in full below:

 SAN FRANCISCO — Facebook CEO Mark Zuckerberg is responding forcefully after incidents in which employees crossed out "Black Lives Matter" and wrote "All Lives Matter" on the walls of the company's Menlo Park, Calif., campus. 
 
 Facebook, whose staff is 2% black, is investigating the racially charged incidents in which the movement's slogan was defaced. Those actions have been a "deeply hurtful and tiresome experience for the black community," Zuckerberg said in an internal post obtained by Gizmodo. 
 
 Facebook declined to comment.

 "We've never had rules around what people can write on our walls," said Zuckerberg in the post. "We expect everybody to treat each other with respect." 
 
 It's a longstanding tradition at Facebook that employees can write on the walls, dry-erase message boards or chalkboards, much as they would on their virtual wall on Facebook. 
 
 "There have been several recent instances of people crossing out 'black lives matter' and writing 'all lives matter' on the walls" Zuckerberg wrote. "Despite my clear communication at Q&A last week that this was unacceptable, and messages from several other leaders from across the company, this has happened again. I was already very disappointed by this disrespectful behavior before, but after my communication I now consider this malicious as well."

 Zuckerberg encouraged Facebook employees to attend a town hall next week "to educate themselves about what the Black Lives Matter movement is about." 
 
 Black Lives Matter began as a hashtag on Facebook after the acquittal of George Zimmerman in the killing of Trayvon Martin, an unarmed black teen, and became an Internet-wide protest slogan after the police slayings of African Americans. 
 
 Today it's a civil rights movement that has taken on a national role in demanding an end to police brutality and mass incarceration. African American leaders, including President Barack Obama, have said the Black Lives Matter's name shouldn't be construed as suggesting no one else's live matter, but to point out a specific problem happening in African American communities. But some politicians and groups, including police supporters who oppose the movement, have rallied behind the #AllLivesMatter hashtag.

 A fraction of the tech work force in Silicon Valley is African American and little progress has been made on the problem. Only 1% of venture-capital-backed start-ups are led by African-Americans and less than 1% of general partners at major venture capital firms in Silicon Valley, the ones that back tomorrow's Facebooks and Googles, are African American. 
 
 The predominantly white male industry runs the risk of losing touch with the diverse nation — and world — that forms its customer base. At the same time African Americans are being excluded from the fastest-growing, highest-paying jobs in the nation.

– Facebook is investigating what USA Today reports are "racially charged incidents" at its Menlo Park, Calif., campus. In an internal memo obtained by Gizmodo, Mark Zuckerberg says there have been "several recent instances" where employees crossed out "Black Lives Matter" on campus walls, where writing is encouraged, and replaced it with "All Lives Matter." The CEO says he made it known last week that such behavior didn't fly, but the problem continued. "I was already very disappointed by this disrespectful behavior before … I now consider this malicious as well." Zuckerberg adds this is a "deeply hurtful and tiresome experience for the black community and really the entire Facebook community." About 2% of Facebook employees are black. "Crossing out something means silencing speech, or that one person's speech is more important than another's," he says. Zuckerberg notes a town hall is planned for March 4 to teach employees about the Black Lives Matter movement. It "doesn't mean other lives don't [matter]—it's simply asking that the black community also achieves the justice they deserve," he says.
