The Ark and The Celestial Toymaker, though? Not canon. Plain and simple. I flatly refuse to let these two into the clubhouse. Doctor Who is not a show in which reactionary imperialist ideology wins the day. It's not a show where the Doctor fights racist caricatures, unless he's fighting someone for producing them. It's not a show about xenophobia and racism. It's just not. And stories that try to make it into one are far, far bigger violations of what the show is about than most of what constitutes a canon debate. The fact that there are far more fans outraged about the fact that the Doctor maybe was in love with Rose than there are about the fact that in 2010 we're still using a racist caricature as a recurring villain is, frankly, disgusting. This is a real and major failing of Doctor Who fandom, and one of the few points over which I feel kind of dirty being associated with it.
