Remove genetic things from lings entirely.

[GORE]

You make them different by substracting stuff that they can choose to do? Does not make sense to me,...
They are not that different.

Blobs cannot use genetics - sure. They are a heck of a lot different.

But if you start with the reason that Changelings should not receive genes because they are not human,...
Then we have to do the same for Vampires and Werewolves...also do not forget Vampire Thralls (which are Zombies...so...which WERE human in the past).
