How about the Monsters-Can-Be-People-Too Manual?
Joking aside, I like Volo's. It is a far more interesting read than the traditional MM. I'd love to see them supplement this approach with a occasional pocket reference book that compiles monsters from previous books of just stat blocks and pictures to use as table references, as the one downside of Volo's is that they don't including as many monsters.
What I don't like about Volo's is that my son reads it then tells me I'm doing it wrong if the races imc act differently from the WotC fluff.
Re the OP, I'm in favour of not portraying any real world ethnicity as inhuman monsters the way Hollywood often does with various groups - white Southerners, Arabs, white South Africans in the past, Russians and various Orthodox and Muslim east Europeans etc. Or Bollywood does with us Brits for that matter! I don't think that is relevant to orcs or drow, but the Vistani fot instance are clearly Bram Stoker's gypsies so I'd like to see a bit of care there.
