You have just expanded health workers to all immigrants. Brexit on immigration is about controlling who comes in, controlling numbers and quality and security. There is not a chance that working EU people will be asked to leave or skilled EU people rejected.
There is a chance. Just depends how badly this pans out. What starts off as racism against a smaller group of Eastern European unskilled workers can rapidly expand. National Action have been outstandingly open that they believe in the original manifesto of the NSDAP. There were people who believed in this before - also in Coventry in the 70s - but they were underground and being surveilled by special branch. They were training for the revolution which they thought would be a left wing revolution and they were to be the underground resistance.
Today, the right is being propagated by MSM ( e.g. mail, Telegraph, Sun ) and there is even a Farage programm spewing out distorted and sometimes totally inaccurate "facts". The revolution these people ( right wing "combat" groups, are training for is a right wing revolution when "we" claim "our" country back.
This is very disconcerting and has arisen because of the raging Brexit debate which has emboldened this scum on the far right.
Theleave propaganda revolts me, but is gladly taken on board by many people.
