I think of it another way. The bill itself isn’t anything to do with protecting children - but lots of people (MPs, charities, campaigners) have been misled into supporting it. It’s what makes “think of the children” the best way to pass bad legislation. Not only does it make it very hard to object to a bill that won’t actually help children, but you get lots of free support from well-meaning people who don’t understand the implications of the bad legislation they’ve been conned into fighting for!
