Thanks Starmer, you're a worthless turd and no different than your predecessor.
Rolling that back essentially makes you a prime minister that believes children should have unfettered access to porn, self-harm material, gore, and that the outspoken parents of kids who've killed themselves after accessing this material shouldn't be listened to. At least, that's how the media (on all sides) would spin it. Not really a fight worth picking.
If their real interest was in protecting children, they'd make a free, publicly accessible age blocking system that parents could choose to opt into, that isn't thrust upon all citizens at once
Given the spread of explicit "give us our pedo games" and "let kids watch porn" voices, I don't think there's any demand for a moderate solution.
And when the moderate solution is actively rejected for a very real problem, nobody has a right to complain when the problem eventually is addressed using extreme solutions.
