Man , you must be fun at parties . Seriously , it ' s a childerns book and as said ' anything more sinister is your personal outlook bleeding into the text '. You can explain every story ever the way you do , but the world doesn ' t get much beter because of it . Lesson from book is clearly that muggles and houseelves ! aren ' t to be treated less than wizards . Just portraying an imbalance in society isn ' t a bad thing to start with . And to comment on it the way HP does definitely isn ' t bad . It actually makes the world more believable and relateable as those problems do exist in our real life lives . But hey , lets not tell that to kids . Don ' t let them explore cultural and racial differences and the problems and tensions they can create . Let ' s shut them out and just teach them the world is made of rainbows , pillows and fairies , that will make them into wellbalanced , thoughtful , friendly adults . I would say Harry Potter can teach kids some valuable lessons about friendship , courage and doing the right thing in an unfair world .
