If they believe his populist pronouncements then Yes. Look, Lineker is a social media influencer who aims to please his followers (virtually calling the tories Nazis seems to have given those followers a big hard on, no?) but if he talks utter garbage then he needs calling out otherwise people would believe him and that is dangerous. Is there a bit of truth in what he says, yes, but there is a little bit of truth in what covid vaccine deniers believe, or climate deniers believe. Basically there is not enough truth in what he says to merit the saying. It's manipulation.
