Flora I do see where you're coming from, totally.
From my perspective if she was introduced as sacha who's come to read to you as she's a member of the community then that's fine.
I agree that introducing her as an actress is going to lead to googling and while it's probably nothing that children of, what, 9 or so haven't been exposed to before unfortunately, her presence in the schoolroom would clearly been seen as approving her choices.
I just think that there's an awful lot of people I wouldn't want in classrooms TBH - I wasn't joking earlier about Gove! So that's the perspective I'm coming from.
Also I don't know much about this woman, maybe my POV would change if I did.
Certainly when people are saying "oh well if you're going to exclude x y and z then there'll hardly be anyone left" then that's fine by me
Children don't actually need famous people reading to them. They just need people reading to them and better Bob from the shop down the road than any number of slebs. Of course Bob from down the road might have made dubious chioces in his past and have all sorts of weird views BUT the children aren't going to find out about them via google the way they will with almost anyone famous.
