Not by themselves, no. Perhaps insofar as they are a part of me, they could be considered to be "alive", but if you separate them from me, then they're not, and (perhaps excluding the brain) they definitely aren't people.
But that aside, I don't see how "yeah, they're people, but it doesn't matter if we kill them" is going to convince anyone either.
I'd say it has a better chance than telling people that they are literally dead inside.
The way that I've been using it, an organ is part of a gray area between "alive" and "dead" where it's definitely not dead but it's also not (by itself, anyway) a living thing. Not sure if you've been using the same definition, and I think we should clarify what exactly is meant by "alive" before we start arguing about what does and does not count.
