To show the complexities of slavery. How about to create a sympathetic group of characters, so that Dobby can rise from them and become a hero after interacting with the main hero. How about adding just adding more evil to the wizarding world for our hero to overcome or rise above? I can keep going if you want, but to stop at racism seems a bit childish if you are serious about writing.

All this did was point out that you don’t know how to read or write critically… unless of course this is satire. If that’s the case keep the course because this is terrifying yet beautiful.
