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.
