I get what you mean, but I disagree with the sentiment of it making real life discrimination look pitiful. There's no better or worse when it comes to discrimination, and I think these types of stories, despite being fantasy, can and do represent struggles some experience in real life. It's also easy to correlate the discrimination seen in this comic only to racism in real life, which is what you also referred to (and I'm not saying it doesn't represent that as well), but I'd compare many of the struggles to disabilities and discrimination due to them - not only physical, but mental as well. For example, the whole thing witv the spiritual beasts made me think of mental disabilities like autism, and how often people tend to infantalise auristic people and treat them like kids, despite being adults (especially if one has higher support needs).
I really hope this series will make people think about the very much still existing discrimination in real life, and its different forms.
The interspecies discrimination in fantasy stories makes it look like our irl discrimination problem seems pitiful. We literally just have different skin, language and religion. At the core, we're all humans. But of course blind people will be blind. And that's insulting to the actual blind people.
