Russell T. Davies doesn't care about black people! And when he does, he's doing it wrong!
Because really, why hasn't any Doctor Who finale-wank been posted? Are all the wankas too busy wanking themselves?
Anyway, Martha leaves. Normally, a companion leaving would be food enough for wank for days! But no, since Martha is the first Proper Black Companion (Mickey being a companion or not is debatable, and by debatable I mean most likely another source for wank) and as she is treated badly by the Doctor, this is clearly because of the possibly subconscious racist undertones in New Who and comparisons are made between how Martha and Mickey are treated versus how Rose was treated.
Other people claim that they are not getting it as Rose and Martha have been both been forced to play a subservient role, and why isn't anyone this outraged about Mr. Jones as a janitor or the domestic violence?
Karnythia explains in a bit of tl;dr that all the black women in New Who are stereotypes, and that all those interracial relationships RTD keeps putting in New Who and Torchwood are EVIL. EVIL SHE TELLS YOU.
ETA: Have an example of wankiness in the comments following Karnythia's post.
And Calapine decides to focus on how Martha was the awesomest companion to ever awesome which isn't wanky, but worth a read.
These are by no means all the links related to the wank, so feel free to add links in the comments!
