Progressive politics is a package deal. It is a political set menu with cult-like or at least communitarian characteristics. It is a tribal political identity rather than a series of beliefs and policy ideas people can weigh up and decide on based on their individual merits. Defending the rights of racial and ethnic minorities is both progressive and objectively right. The same is true of cutting carbon emissions and seeking greater economic justice for the poorest people in society, but the same cannot necessarily be said of other complex legal and social issues.
Boris Johnson, our new Prime Minister, is a man who shamelessly stood in front of a bus during the Brexit referendum campaign and told voters that leaving the European Union would return £350 million every week to essential public services like the NHS; all the while knowing this was untrue. Since moving into Number 10 he has repeated over and again that his government is engaged in ongoing negotiations with its European partners, when the European parliament and commission have unequivocally stated this is not the case.
