I also dislike the "we are the only school" rhetoric, but do think she was right when she raised systemic issues about behaviour and expectations across the system as a whole.
I still have discussions with colleagues that go like this:
Them: We need to look at what we teach Y8. Lola, you have bottom set. What should we do to engage the boys?
Me: a high quality text with enough time to focus on improving particular areas. We could have set standardised pieces, but beyond that each teacher could use the text to develop their group's weaknesses.
Them: that sounds nice, but what about boys? We also have a PP gap which we need to look at. Maybe we could do a project linked to football? Visit a local football club and do some writing.
Me: or we could pick an appropriate text and teach it well instead of sending a message that our disadvantaged students and boys aren't suited to English?
Them: maybe something about war, or Stone Cold, that'll engage them, something edgy, something topical.
Me: it might, war poetry could be good. We could get an anthology and look at how representations change throughout WW1
Them: or we could get a documentary about PTSD and war and they could write like they're a soldier.
Me: that could be interesting if we looked at shell shock, PTSD, soldier experiences, attitudes to mental health. We could do some good non-fiction coverage. What's the main focus of this scheme of work going to be so we can narrow it down?
Them: to engage the boys/PP
Me: what's the main curriculum focus though? Do Y8 need more poetry, or more non-fiction? What's our weakness area at KS4, could we start addressing it early?
Them: we need to address boys not doing as well, and the PP gap
Me: so the whole of Y8 will study a scheme of work with no curriculum justification other than 'we think war and shooting people will engage boys and disadvantaged pupils'?

I think KB is good at pointing out that a lot of schools have avoided challenge, particularly at KS3. I also think she's right that there are lots of schools where it's warning after warning about behaviour and it affects learning. The phrase low level disruption should be banned in my eyes because it's disruption.
