However, the main objection to decolonisation is not that it is false but that it is narrow-minded, obsessive and intolerant. People will continue to disagree about the prevalence and the origin of racial prejudice. Error and discord are inevitable hazards of the free market in ideas. But the decolonisers are not just trying to defend their views. They are seeking to upend the free market in ideas by imposing them. This is a natural consequence of their approach to intellectual inquiry. For those who believe that knowledge and truth are mere social constructs there is no point in debate. Alternative visions of the world are just the product of social conditioning. Social change and suppression of dissent are the only answers. Schools and universities must be the battlegrounds. Hence the obligatory decolonisation statements, the imposition of a highly controversial agenda on the syllabus, the no-platforming of opponents and the real fears of so many academics that if they step out of line their careers will be blighted.
