The question in question is To what extent are half-breeds treated as humans?
I agree with KRyan that the older question(s), while duplicate, is/are not written or supported nearly as well as the new one. I know that sometimes when that happens we dupe the other way with answer migration. Is this a good use-case for that? Can we do that?
Specifically, can we move things around to close Do the Elf Blood racial trait allow you to fulfil "being an elf" prerequisites? and Can a half-elf take human traits? as duplicates of To what extent are half-breeds treated as humans?
