I cannot resist noting that I am totally uninterested in association football but, owing to place of birth and upbringing, I am a birthright Tottenham supporter. And Tottenham is, for many reasons, perhaps the least racist football club. And until the vast injection of money into football, it probably had the best educated supporters. (When I was a kid quite a lot of the Orthodox Jewish supporters lived within convenient walking distance and had season tickets so they could attend games on the Sabbath.)
Unusually I find myself with @Nobby_Stiles on this. Rowling’s world is one in which some people are born to enormous privilege while others accidentally acquire it, and she’s absolutely fine with that. The non-privileged people are subject to a kind of apartheid, and the fact most of them are unaware of it is irrelevant. In the days of the British Empire, the more aristocratic foreigners acquired British privileges just as rich subjects like Saul of Tarsus could buy Roman citizenship. The idea that all people of “our” class must show class solidarity regardless of colour or origin is not particularly meritorious.
Compare it with Terry Pratchett’s word in which (plot spoilers) Vimes is in many ways the voice of ordinary people, and eventually (in Unseen Academicals which, like Snuff, is heavily about racism) Vetinari is able to show off to the aristocratic Lady Margoletta how in Ankh-Morpork ordinary people are now invested in citizenship and public spirit.
It’s clear that in reality in Rowling’s world once the bad guys started to attack ordinary people things would be different - military doctrine would quickly identify that the number of the enemy was small and so overwhelm them by attacking with so many different routes that they could not attend to them all. A group might be able to stop one drone, if they knew what it was. Their chance of stopping a simultaneous attack by dispersed artillery with short range missiles supported by laser guided bombs would be zero*. (Again, interestingly, Rowling seems unaware of the laws of thermodynamics, while Pratchett does not allow magic to function outside physical laws.)
*I had this discussion with an officer in the RA, so it isn’t a completely unbiased viewpoint.
