Lmao that might be the weirdest example I've ever read. Disabled people should be treated like the sons of kings? What does that even mean? Why can't we just treat them like normal people?
From what I can see, the story is likely modified to accomplish certain political goals - i.e. the name is likely changed, and the disability itself might have been added later to demonstrate him not being a military threat. But at any rate, the reason he was welcomed in was because of his lineage, not his disability (if he was actually disabled at all).
Anyway omw to go offer Halli some free food?
