Gareth,
Try giving statistics for about 40 years ago and I'm sure that you will find that the Welsh language was systematically focused for destroyal.
The UK establshment paid Millions of pounds to do so. I'm sure every native Gaelic, Welsh or Manx speaker over the age of 70 will give a similar harrowing tale of how their (our) language was almost forced out of existance.
Our aim is for survival and revival of our indigenous languages. Is that such a big threat?
