Sounds like any changes from a white bloke would be considered 'ticking boxes'.
And it sounds like YOU are just trying to cause an argument where there isn't one, but instead jumped at the first chance to take a cheap shot rather than consider what I said. Funny that...
If you'd paid attention to anything I said you'd see that I'm an advocate for change, just as long as it's not a forced, hamfisted attempt. For example, the same people crying out for a female Doctor are also coming up with a dozen or more theories as to why Missy ISN'T the Master. Why? Because they don't like her character, don't like the Master being female, that she's all 'wrong', you name it... yet they continue to insist that they'd be happy with a female Doctor when (yes, "when" not "if". It will happen, sooner or later) they get one, when by their own actions they're proving they'll never be satisfied because they want change on THEIR terms, not in a way that naturally compliments the show - they want control, not change, and that's just never going to work out for the best.
Personally, I love Missy and think the Master's regeneration/resurrection into a female suited the character perfectly for a couple reasons which - since you obviously need everything spelled out for you to remove ammo for your petty sniping - are these:
1) The Master is crazy, always has been, always will be. Sure, s/he can be cold, cunning and calculating on the surface, but deep down they're irreversibly insane and always looking for ways to outsmart the Doctor. Yet when two Time Lords meet they can both sense they're the same species (from "The Sound of Drums," though there has been much evidence that this isn't always 100% true, as the Doctor has failed to recognise other Time Lords in the past, or they him, whilst at other times he's told them apart from the very beginning), so naturally the Master would switch genders at some point to confuse his nemesis, to not make his identity so easily deduced next time they met. Hence why Twelve couldn't immediately tell Missy was Gallifreyan, let alone the Master.
2) It's said that a Time Lord can regenerate into the other gender through either extreme focus (The Corsair could apparently do it easily, according to Eleven) or due to a traumatic death (The General regenerated
back into a woman when the Doctor shot her to save Clara, but seeing as how the Time Lords had only recently survived the harrowing Time War in
her timeline, it makes sense that whatever she experienced during it brought upon the regeneration into a man. Also, when she
did stand up, the guards were only slightly taken aback by her gender, meaning it's not that uncommon or unheard of). Now, if you ask me, having your entire body and life torn apart by space-time itself AS you're being attacked by a time-locked-insane Rassilon would be traumatising for anyone, even someone as mad as the Master. So, he wakes up to find he's now a she, and her immediate reaction is how she can
really mess the Doctor now.
3) Moffat, bad as he can be at times, took an ENTIRE SEASON building up the mystery of Missy and who she was whilst at the same time laying out clues that - when you look back at it (she's able to pluck people from time, any time, moments from their death, and is making them into an army of Cybermen, etc) - scream the words "Master Plan". This made her entire character, her entire purpose and reason for being female organic and natural to the story, and not just thrown in without a thought. He knew Time Lords could switch genders, had even hinted to it in past seasons, yet worked up to the revelation in a way that made for one of the best twists in the show's last couple years - heck, since "You Are Not Alone", in my opinion!
So, if that much attention, care, detail and thought can be put into the female-regeneration of the Doctor's oldest nemesis, surely his own eventual gender-transition deserves it even more so? I really REALLY want to see it happen, but I don't want to see something so monumental executed so cheaply. The same goes for regenerating into another ethnicity (again, something the General's recent regeneration proved possible). All I'm saying is that the majority of people campaigning for the change just want to see it happen ASAP without actually caring how or why it will finally happen. But if proper consideration and respect isn't put into it, it's just going to backfire terribly.
But please, find something else in this reply to bicker about, since that's what it "sounds like" you enjoy doing...
I'd really like them to not go with Kris Marshall. Nothing against him, but in a universe where a time lord can regenerate as anything, it seems disconcerting to me that for 13 times, The Doctor has been a white man.
Same here. Kris is a good actor, able to balance comedy and drama, but if anything I couldn't see him able to portray the Doctor in any other way than a lankier Smith. Something does need to change, and I only hope Chibnall and Capaldi come together to find what the show's been missing all this time.
On a side note, did you know that Time Lords can apparently change their physical appearance in terms of species when they regenerate, and that the main reason the Doctor regenerates into distinctly humanoid counterparts is because he spends all his lives around Earthlings? Theoretically, there's no law against a Time Lord regenerating with the physical features of a Silurian, or a Catkind but, prosthetic costs aside, I can't see that ever happening to the Doctor - at least not on the main TV show.
(see what I did there? See? See what I did?
