A people or a class which is cut off from its own past is far less free to choose and to act as a people or class than one that has been able to situate itself in history.
As cultures, oppressed by immigration and fearful for their identities
endeavour to situate themselves in some sort of history
ie rights that have been fought for and won by people giving up their lives
the electorates in the UK and US have used their votes as the paving stones of revolution.
