Most countries have signage in more than one language. Only in Scotland is it a problem and only then among a minority of Yoons who tend to be insecure and monoculturalist in outlook.
Most other countries are bi-lingual. The UK has failed miserably in this area due to British exceptionalist mindset. Other countries rightly look down in the British for only being able to speak one language.
So the SNP who have been in government have kept the insecure and monoculturalist outlook even though they are in complete control over education....yet its not their fault?
Figures.
