Is it OK for White People to Post Photos with African Children to Support BLM?

Educate me my fellow men, Does the Black Lives Matter movement actually care about lives of other color? My question has nothing to do with race or people? My question pertains to the movement and cause itself. Don't the people who lead this cause only care for their own movement and care nothing else but their own objectives? Which may not be at all about Black lives? Examine their words and actions and you might just be surprised that though the intentions for sure are dark but it is not about Black.
