This paper addresses responses to news about the imposing of a local lockdown in a UK city. The opposition to the measure shows it to be controversial as does the associated rejection of the grounds for taking action against covid more generally, which comes alongside the devaluing of expertise, resistance to public health responses, a proliferation of conspiracy theories and misinformation and the harm that can be caused by focussing on non-adherence to covid measure. The research question for this analysis (...) is therefore: how are arguments about the local lockdown discursively formulated in online discussions? Discursive analysis of online discussions following four newspaper articles identified six arguments used that range from scepticism to conspiratorial: scepticism over (1) the prevalence and; (2) severity of covid; (3) lockdowns generally do not work and (4) the specific city lockdown will not work; (5) lockdowns are overly risk averse; and (6) there are hidden political motives for lockdowns. The discussion shows how both the ‘conspiratorial’ and non-conspiratorial arguments are potentially harmful from a public health perspective. (shrink)
