TODAY, IT WOULD BE COUNTED AS DISCRIMINATION
I come from an era when those trained as teachers had to model correct speech to students. This included pronunciation, diction, word choice usage and overall clarity.
Part of our training was that speech imperfections (i.e. ‘rabbits sun wing around Wocks’) had to be overcome before graduation. For those with speech and speaking challenges, corrective and elocution sessions were offered. They were free and compulsory.
It was deemed that teachers who were to teach students had to, for example, correct speech and speaking.
We have moved far from those days, but I still think what we were offered was invaluable.
