Diverse casting is in fact the laziest form of racial inclusivity possible. PLEASE make movies and series stemming from African tradition and mythology, and rightfully cast black people for that. The problem with forced diverse casting is that I can't bring myself to imagine how and why dwarves/elves/etc.. can be both black and white, since they all come from the same land in the LoTR lore. At least pick a lotr race - skin color pair and only cast people of that skin color for a determined race, I'd be ok with that. It just messes the lore for me, nothing more nothing less.
