You say I repeat myself, yet the links I post above relate to fresh stuff that hadn't been aired previously.
On the island of Ireland, including Northern Ireland people have the agreed right to have an Irish passport.
So if the reports are to be believed, you can be living legitimately in Northern Ireland, hold an Irish Passport and as a result you can be discriminated against getting a job on the Border Force in the place where you have lived and grown up all your life.
Discriminated against because of your passport, because you're not 'British' in a documented sense.
Maybe it would turn out to be those jobs initially, and once the precedent has been set other jobs would be included.
One example would be holding political office.
I feel certain that there are members of the Northern Irish Assembly (when it is up and running) who would have an Irish passport and not a British one.
What with the Windrush scandal bringing these questions of nationality and rights back on to the agenda, and fuelling the unease felt by EU nationals (including citizens of the Republic of Ireland), and most especially when these issues are translated into practical realities of job losses, and denial of treatment for example, then it becomes yet another way of viewing the impact wrought upon us all by those who voted for brexit. I see the details regarding the Irish border as one of practical realities.
The obvious common denominator is the 'otherness' of mainland EU nationals, the Windrush people and the Irish. It is possible that the definition of racism is a moving feast, but these issues seem to me to be heavily associated with matters of racial discrimination whatever 'technical' arguments are assembled to say otherwise.
Those who voted for brexit ushered in some of this stuff, and for some brexit voters the response to my continual raising of it is to put me down in a myriad of ways, to wash their hands of their responsibility for what is happening, or assemble an agenda where certainly something like the Irish border is at the bottom.
