The more we allow racism a voice, on QT over Brexit, or in the right wing rags with MM, the more acceptable it becomes.
'We', aka the UK, need to revert to the loud NO we gave to racists prior to Brexit.
Having experienced living in the US, I used to be proud that the UK was less (not totally non) racist. Unfortunately, the links between Brexit and the extreme right wing of Farage and Steven Yaxley Lennon et al have made those that were previously aware their attitudes were unacceptable other than in their little coverns, feel they are agreed with by the general public.
Banish them back to their filthy little lairs. No publicity, no air.
