A female doctor would be a travesty. I don't know why there's always this big thing about a female doctor. It never happens.
I'm also shocked to see the vast majority of people would be okay with it. I think it would be awful. It would be cheap and tacky. If they had a female doctor, I'd strongly contemplate not watching the show. I'd probably make my own fan fiction canon where the Doctor regenerated into Idris Elba or Damien Molony as a way of coping.
