I think this is just trying to get ahead of the curve. ie they are obviously counting on Strike being an important part of the autumn programming. Prime time sunday slot pushing the last episode of a suitable boy onto a monday evening.
There was also a cringing article with the lead actor and actress in which both waffled on about what a nice person she was but wouldn't say anything about the trans issue.
I dont have much sympathy for the BBC but they must be aware that this will be used by trans activists to have a go at them.
Suspect thought that 90% of the audience who will watch on sunday have no interest in the debate at all.
What will be interesting is the tabloids who use tv programmes as a source of "news" will give it much coverage or decide they dont want to take the flak any way.
I will be watching to show my support for JKR!
