Why do people do this - say those that don't agree with them have no brain?
Welsh is an important part of the culture of the British Isles and the Welsh are rightly proud of it. But some Welsh people who do not speak Welsh do talk of layers of prejudice in Welsh society to the Welsh without Welsh. An example I know of being a large cultural organisation (very large) suddenly deciding its annual address should be given in Welsh. Many English people also work for this orgnaisation. The person next due to give the address was actaully born and brought up in Wales yards from the head quarters but is Welsh without Welsh. He was furious - said he was made to feel like he was not really Welsh in his own home town. The Brecon Beacons is not in a strong Welsh language area I believe.
The change is a political act on all kinds of levels so some will react politically.
I don't disagree with the change as a such but it is probably another example of political change being forced from above, of people in an arts or cultural orgnaisation doing the nanny knows best thing - was there any local campaign to change it with any indication of wide spread support for example?
Another factor pointing to this being a political act is this:
"Catherine Mealing-Jones, the chief executive of Brecon Beacons National Park, said: “We’re an environmental organisation. We’re trying to cut carbon and push to net zero. So, having a carbon burning beacon just isn’t a good look."
It is an incredible stupid justification and clearly the worst kind of virtue signalling. As though beacons anywhere in the UK have ever been a serious cause of climate issues or that they are anything other than occasional and historic. It just makes the management of the park look stupid.
As I say I think if (if??) there is local support why not change the name but I certainly don't think those complaining have 'no brain'. On a slightly side note I do think there is a strong argument for Welsh being taught in English schools - that would help people in England come away with the pronunciation at least and provide support for an important language.
