What complete rubbish. This article in The Telegraph is such a waste of time (pardon the pun).
Just because something has it's own cast, it is classed as something that it's not so it becomes racist or sexist or something ist against it.
Doctor Who And Race?
What are the Felinetta, Sontarans, Dalek and even a Time Lord, he's not even human!
Who honestly gives two hoots about it. It's crap and really shouldn't be published in anyway as it's against creativity and free thought. Infact the person who ever thought of it as a subject matter really should have their head read.
