Remove "by human beings" from Law 2

I absolutely think that instead of changing the laws, we should instead just change the ruling that genetics mutantraces are not human.
It is extremely confusing and weird for everyone involved to have nonhuman people you are not allowed to murder, and considering that they are still humanoid and that a human can be turned into one via activation of a single gene, it seems reasonable to me that they are just subspecies of humans.

I think this would especially simplify things for newer players.
