Only a generation ago, signs in British pubs and boarding houses reading: "No Irish, No Blacks, No Dogs" - were not an uncommon sight.Now by my reckoning generation is about 20-30 years and I very much doubt that these signs were around in the 1980s. In fact I doubt whether the signs were ever a common sight. Think about it, in a country with a large ethnically Irish population like Britain putting a sign like that in your window would be like painting a target an saying "Throw brick here". The sign has about as much basis in reality as the "No Irish Need Apply" signs that supposedly existed in the United States.
It's also rather strange to see that whenever someone shows an example of these all too common signs it's always the same sign, in other words one sign was put up once some time in the 1950s and the left uses that to propagate a myth of racial oppression. Actually the letter writers don't even go so far as linking to the solitary genuine example and instead link to a book by the Sex Pistols frontman John Lydon. In a world where the fictional incarceration of two make believe stoners is evidence of the inherent racism of the USA this is actually a relatively high standard of proof.
The paternal side of my family came over from Ireland yet they appear not to have endless tales of oppression, it turns out that the oppressors chose to target only those whose children and grandchildren would find it quite useful to identify to a persecuted group. Whether this is because left wing politicians and their groupies are bare faced liars or because parents with a strong disposition towards cultural self pity are likely to produce little race hustlers I do not know. The ironic thing is the creation of a narrative of racial victimisation is almost exactly the same as what the BNP do gain recruits.
