The Mail‘s Science Editor Michael Hanlon can be relied upon to recruit even the most obscure and disinterested branch of science to the cause of rampant political correctness. Today he takes on the ‘loony’ planetary scientists who want to ‘demote’ poor Pluto, removing the plucky planetoid from the list of proper planets all together. He provides a reasonable summary of the science but manages to sign off: “There are few enough certainties in life. Please, let’s keep little Pluto as one of them.” Brilliant. Quite brilliant.
