This uproar has a powerful whiff of tabloid papers and populist wannabes stirring up public indignation, as they are wont to do. When I see them I like to dig around a bit to see what's going on. I haven't seen the show so I can't make a fully informed comment. But I can pick up some hints.
Firstly, the Tobacco Factory in Bristol isn't some fly-by-night fringe theatre, it's a community-based arts space created by George Ferguson in one of Bristol's old tobacco bond warehouse as part of the regeneration of the run-down south side of the city. George Ferguson is the former independent elected Mayor of Bristol, a one-time Merchant Venturer and a generally respected figure around the city so I can't see him overseeing the presentation of smut. Actually I have seen 5-year-olds attending a production at the Tobacco Factory once: it was a very orthodox staging of A Midsummer Night's Dream. You can imagine the thinking, it's got fairies in it so the kids'll enjoy it. The kids were bored to tears and getting fractious.
Secondly, in the small print of the show's website it says it was created in collaboration with the School of Sexuality Education, whose own website declares its aim to be to "[...] support schools to provide age-appropriate, inclusive, trauma-informed relationships and sex education programmes.". As I said, I don't know for sure without seeing the show but I get the strong feeling that it isn't about grooming and sexualising children, it's about stripping away all the furtiveness and shame that we've all been brought up to associate sex with. It's the furtiveness and shame that the child abuser trades on. If the show is saying, there's nothing dirty about your body, it's all right for you to explore it when you're on your own but it's not all right for Uncle Kevin to touch you especially if he says "let this be our special secret" then I'm fine with it". Anything that stops child abusers getting away with it, as they do all too often because they rely on the child's shame, is fine by me.
