You know the story of Rudolph the Red-Nosed Reindeer, is so freaking messed up, and by that I mean I'm going to go on a big old rant about this. The blatant ableism and basically hate against anyone who does not fit into society's norms. The themes of them being something to hate and scorn till their differences are profitable and are able to be used, no regard for that this is a person and only about how they can be exploited.
With Rudolph it's very obvious. Santa is like he will make a great reindeer to pull my sled one day, and then the nose glows and he immediately goes that is bad you can't pull my sleigh if you have a glowing nose like that you need to be normal. And then his parents think he is broken or wrong for it, maybe a little less his mother but still both of them are very much hoping that it goes away and if not they're going to hide it. We can see his father tries to hide it make it so no one notices his difference and teaches him to be ashamed of his differences. Then when others see his nose they laugh, even the adults laugh. Everyone dislikes him for being who he is, besides Clarice. So after being tormented he runs away, like most people do and feels that he is a mistake for existing. And I know most of you have seen the movie or at least heard it and so you kind of understand what goes on he meets other people that are different and not quite what most people considered normal and feels less like he is wrong. He still feels like there is something wrong with him, especially after his nose leads Bumble to them. And yes his nose was alerting danger to them, he feels like it is all his fault and he is just a burden. So he leaves to try and not burden others. But he probably reacted so strongly because of how people treated him before. When he is away from people he starts to realize hey I'm not just a burden, he still feels it a little but he's not totally convinced that he just a mistake. He proves to himself that he can survive that he is strong and grows. So with newfound confidence he goes back to try to confront his fears. The people there still treat him horribly. Then he finds out that after a while his parents and Clarice go searching for him. His friends save him and the others using there oddities. And when he gets back he finds out that Christmas can't happen because because of the fog being too thick and then he sees Rudolph's nose can cut through the fog. Then Santa complements Rudolph over and over again to get him to help him through the fog and everyone suddenly becomes nice to his, saying things like I knew your nose was going to be helpful.
