Technically, it's a "political" statement, as BLM has repeatedly called itself a "Marxist" (Communist) organization and thus Marxism is a political affiliation. At no time has BLM "ever" condemned the black on black violence within their own communities. Their belief and statements have said that "blacks CAN commit crimes" and "what do we want? Dead cops." It doesn't matter that 98% of law enforcement are good people just doing their jobs of enforcing the law....equally.It's a protest statement
Companies/Corporations can stipulate "dress-codes" for their employees and restrict political endorsement while on the clock.
