It's catching on, the gov spend millions on it. There's a lot of anti-English [people] sentiment which feeds into not speaking English (just because of the name of the language rolls-eyes). Gov jobs require it, despite not needing it. Middle classes use it to get kids into Welsh school and away from the poor performers and chav-y types.
There are more daily Urdu and Mandarin speakers in the city I live in than Welsh speakers. Indeed, I work in a store and the only welsh language I hear is from educators speaking to their kids.
It's probably the thing that would/will push me to move or seek alternative education (eg home-ed). I don't see Welsh language as being important enough to be a part of every school lesson.
What you call "not speaking English" I'd just call "speaking Welsh". Your framing such self affirmation gestures negatively, as an aggression to the other, only shows your bias. The world will hopefully keep one more language around thanks to the people that make that perfectly legitimate choice. In any event, I bet any adversary feelings towards the English language are not due to the name but to the fact that it's been dislodging Welsh out of existance, as your reasoning illustrates.
A Gov employee should be expected to know all official languages in the country where she'll be serving. Especially if she is going to have to face public.
Considering to move or home school your children only to keep their minds uncontaminated by Welsh sounds more like political or social prejudice than actual educational concern. Trust me, knowing Welsh will only make it easier, not harder, for them to learn Urdu and Mandarin. In Spain, students from nations with one or more languages of their own average a higher proficiency in foreign languages (including Castillian, AKA Spanish) than those of monolingual provinces.
