I'm not using any metaphor in order to "have to be right." I'm simply pointing out that it is lipstick on a pig, which it is, and pointing that it's not a half-elf(which is explicitly half-elven and half-human) if it's fully human or fully elven and just looks different.
It's not a matter of right or wrong, but rather a matter of what is or isn't. If folks want to discuss different implementations of half-elf mechanics, because they don't think it has been represented well up to this point, that's a different discussion. While I am happy with how it has been done up to this point, I'm open to the idea that it could be better with other mechanics. I don't know what those mechanics could be, but that's what the discussion would be for.
