A phrase created by writer Douglas Murray on
Metropolitan Police’s former assistant
commissioner Mark Rowley, indicating a false equivalency that serves a dishonest political purpose. To quote Mr Murray:
"Mark Rowley embedded the idea that the UK faces an equally balanced challenge: Islamist extremism
on the one side, far-right extremism on the other. In order to sustain this equation it appears that for the time-being one must draw a moral equivalence between Muslims who blow things up and non-Muslims who do not, but have mean views. And an equivalence between Muslims who call for murder and non-Muslims who do not. "
Rowleyism is giving equal or similar weight to both or using one to decontextualise the other
