See, I disagree. I don't think that they have to differentiate between the two. Simply saying "Black Lives Matter" should be enough.
When I say BLM, I'm not necessarily saying that I support the organization. I'm simply saying that my life matters. It's very frustrating for me to see fans praise these young men every Saturday during the fall. When these young men want to be vocal about the racial discrimination they're faced with these same fans respond with "I've lost all respect for Auburn" or "they're no longer getting any of my money".
