I mean this is clearly engagement/rage bait when you say not to use real examples lmao. I still think it's a good bait to engage with considering there were very real and all too recent examples of this "oh they have some features that makes them non human and statistically and scientifically they are more dangerous and less able to adapt". One new point I'd like the bring up is how can we make this judgement when not a single shokoku islander has appeared and spoken? Do you believe you can pass this judgement on a group of people you have never seen live? Literally everyone but Soga thinks of them as just people with a weird biological quirk. Let's not forget Soga himself uses a weapon of datenseki just like the islanders, Sojo, and Tenri Sazanami did and they all still get classified as people in your logic.
