Its quite pathetic. I think we live in a bilingual country and should celecrate and cherish it as it is not fight over some sort of welsh language superiority.I also think the welsh nationalists and welsh language activists should remember its not been long since children were taught no welsh at school ( I did 2 years of 2 hours a week... hardly enough to learn anything)
Rightly people should be able to recieve information in welsh or english, street signs should have both english and welsh on them etc.
Like it or not if you implement a welsh only policy you will cost this county millions as its now becoming a properous, cosmopoiltan nation after decades of being marginalised ( by the english).Trade will fall if you wont trade in english or do business using the english language. Nobody else in the world is going to go off and become fluent in welsh in order to do business here,take a holiday here or visit for business they'll just avoid coming here.
You have to face facts. most people in Wales dont speak welsh as their first language. By all means cherish it, encourage its use and teach it in schools, offer free courses to whoever wants to learn ( all of those happen already) but forcing english speakers who are welsh born and bred to use welsh will cause a mass revolt against the langage. It would be counterproductive and most english speakers would simply react in the same way that the welsh did when english was enforced years ago, only now I expect far more militantly.
