Have to say, Pitch, that makes sense to me. I have worked with abuse survivors and am aware of the dreadful impact of abuse - and, sadly, am also aware that the problem is nowhere near limited to one or two schools.
I'm all for talking about it, tackling it, opening closed systems and naming what needs to be named.
I'm not sure that avoiding a few specific schools is ever the answer. I don't have sons, and if I did I probably wouldn't be sending them to an indie school anyway, but several (very aware) parents I know are sending their sons to CC or similar schools, and they are taking the view that getting involved and tackling the issue by openness and questioning is more useful, ultimately, than blacklisting and avoiding.
I do have daughters, and similarly I'm trying to teach them how to trust their feelings, respect their bodies, and talk talk talk if they ever feel uncomfortable or manipulated. I have no idea if they will come across potential abusers, though obviously I hugely hope not - but there are damaged people in every walk of life, so I want my kids aware and in possession of strategies. And I will talk to whatever schools they go to, get involved, try and have a positive influence on the community ethos in favour of openness and awareness.
