......so he's applauding his own profound political bravery in not killing off the show's only regular male character of color, which character got continuously derided as an "idiot" and useless and a "tin dog" and a "zero" through his entire run and had to get away from the Doctor in another universe to develop any sense of self-worth?

um... yes.

And if Rosita makes it to the fifty-minute mark of the Christmas special before biting it, I'll be sincerely shocked and I won't be the only one.

i actually think she will make it, possibly because it would be so very blatant if she didn't? pssibly because i also have this feeling, from the CiN clip, that morrisey!doctor and rosita are going to be intended as a broad parody/commentary on doctor/companion in the new era, and so he will probably have something cracktastic happen to her, but not death. i think nos is probably quite right when saying, "she's got rose's name, she's black like martha, and she has breasts. donna had breasts."
