This is why I suggest that we should be thinking in terms of prohibitions rather than rights. (see post 1) Suppose we ban or sanction violent video games? Is this the same as giving human rights to computer-generated characters? Not really, but it has the same effect.
The point is not to protect soulless things, but to prevent feeding raw meat to those with violent appetites, even if it is imaginary.
I get your drift now. For example a sexual act on a robot appearing to look and act like a 10 year old girl. Although I see the logic of your position, a prohibition would make fare more sense to me than robot rights.
