I was deeply shocked today to hear rumours that the next Doctor might be a doctoress. I hope that readers will join with me in strongly opposing this complete redefinition and consider the dangers and unforeseen consequences which this tampering may bring. For a start a female doctor goes against all our established understanding of time travelling itself. A dashing, deep voiced male is the right and proper figure to be striding across the centuries, not some girl batting her silly curled eyelashes. This ridiculous pandering to contemporary ideas will not do; how is some female going to have enough natural authority to command the respect of previous generations or to quell alien races. I think she'll be too busy putting on her make up!
Readers can all observe the clip below in which the doctor regenerates properly into a man. He does have a moment when he thinks he might be a girl and his distress should be enough to demonstrate that Doctors, just like the rest of us, are happier when they don't face any nasty surprises which go against the natural order. I sincerely hope that, should the unthinkable ever happen, there will be proper provision for those of us who know that the Doctor can only ever be a man. By proper provision, I mean a completely separate programme on another station so our world can stay unchanged.
In any case, you can't change the rules of regeneration. Tradition and experience tells us that the Doctor always comes back male. We'll completely open the floodgates once the Doctor's meat and two veg morph into lady bits and there will be no going back and no knowing where we are. And if the Doctor can become a girl, what's to stop him regenerating into two Doctors, or three, or four? We could have poly-Doctorism on our hands before we know it. Just imagine the confusion and the potential for disaster.
We rely on the Doctor! He has saved the world in the past. Don't let them do this! It could be the end of life and the universe as we know it...
