Historical frameworks should open discussion

Political and historical debates become unproductive when people retreat into groups that only agree with them. The first recommendation is to read the underlying legal scholarship rather than rely on newspaper summaries or partisan descriptions. Critical race theory is treated as a possible starting point for discussion rather than a doctrine that every historian must accept in full. Britain's own imperial history makes that scholarship relevant there even when a reader rejects parts of the framework. A framework earns value by helping people ask and test questions, while shutting down debate defeats that purpose. Resorting to personal insults indicates that an argument has run out of substance.
