The reason I don't want the next Doctor to be a woman is basically because I'm a Doctor Who nerd who got into reading Doctor Who books when I met Mr BC.
In the books each House of Gallifrey was given a Loom machine which produced the children as natural births were considered beneath them.

The loom machine "fixed" the sex of each child produced and only permitted a certain number to be "born" to each House at any given time.
Also there are many women Timelords from the cannon books/ audios they could introduce to the series if they so wish.
I was pretty pissed off when they introduced Missy as The Master as it was to me an easy cop out. Like she couldn't just be an evil twisted female Time Lord in her own right.
I'm hoping it will be an older male Doctor, don't care what colour skin he will have.
And Harriet Harmon can go sit on one for saying that the next Doctor should be a woman and have a male assistant “She has got to just tell him what to do, he will need that leadership.” She's just being a sexist bint.
She has missed the bloody point about what it is to be an assistant to the Doctor. It's about keeping the Timelord sane, grounded and make him a better "person", not about telling someone what to do just because they are of another sex! To a Timelord we are not male/ female, just humans (it was only RTD who tried to romance it all up).
