Sorry, Sidhe, but that's quite a reactionary view. Zombie aliens, in their own way, are no different from you and me. Well, certainly not much different from Curt Sibling at least.
They need understanding, not condemnation. Have you ever sat down with one of these zombie aliens in your own front room, sharing a pot of tea, and tried to communicate with them, understand their wants, their needs, their desires ? I think you'd find it a lot easier to understand them, than, say, VRWCAgent.
Zombie Aliens Need Your Love.
