Yes, it is racist to ask people to treat blacks the same way they would treat whites. People totally miss the point that the saying is that black lives matter, too. They are not "less than" others. Wanting to be treated justly isn't racism or pointing fingers, it's a request that someone who has it easier in many situations because of their race maybe consider that it is no loss to them to acknowledge where people can improve. if that hasn't been adequately communicated to you until now, that is sad. But it does not make it any less true, no matter how you perceive it has been communicated.
