It’s been established that the Doctor comes from a race where gender and orientation does not exist, so he can be anything you want him to be.
This is NOT new, it has been known for 2 years. We will see how the new Season is. The Specials: 1 was woke crap. 2 was really good Clasic Doctor Who, and 3 was good.The Woman doctor was horrible, not because she was a woman, but because she was a weak doctor. I cam take a LITLLE BIT of wokeness if the Doctor and Companion are good.
And changing the number of times a Time Lord can regenerate also ruined the show.
Look what happened the ORIGINAL MASTER tried to come back a thirteenth time, against the law, in the original series!
