Bonsoir
"I don't think that "racism" is the right term, Himalaya."
Well Irish and Traveller are both classed as ethnic groups for the census I think, and in lots of equal ops monitoring, so I think it applies.
"Personally, no, I think the opposite: it would be discrimination for schools and teachers not to teach standard English pronunciation (why do some pupils not merit being given access to standard English and others do?)"
But schools don't teach standard English pronounciation (if there ever was such a thing) they don't teach pronunciation at all (otherwise there wouldnt be regional accents). My son's teacher in the home
counties is from Lancashire. They've all learnt how to mimic her quite well, but it's not on the curriculum.
Even for non UK accents - There have been kids in his class from India, Trinidad, Japan, France... No one suggests special pronunciation classes for them to correct their accent. As long as they can speak and write with standard grammar and spelling, and be understood in their accent no body sees it as a problem.
