Actually I will counter that something can be undead and not horrorshow: case in point the very video that gave me the idea was the Zombie bullying PSA. I feel it is comedy and zombie oriented, but not necessarily horror-inducing. I mean yes, zombies can be considered part of the horror genre, but I would say that many channels have sub-categories that are specific enough to stand on their own.

For example, there are videos of zombie-parasites that I think would be fun to put into this channel as well.

As for the whole argument that this will cause confusion between 'dead and 'notdead, I get it, but really people who are declare videos dead and not dead are pretty smart and I don't expect a sudden epidemic (pun intended) of misused *undead tags. I mean, if it becomes a problem sure nuke it, but I doubt it would...
