Acknowledging the realities of structural and institutional racism is hard for conscionable white people. It might ask them to consider how they're personally implicated, or have gained from systems that have oppressed and rejected others. It might require them to take a next step. It's easier to say, "I don't see race," or to dismiss the Black Lives Matter movement as structureless and theatrical than to embrace and promote its most basic premise, which is to believe that black lives have worth.
