there is a claim that more people speak Welsh than ever before in its history. What they really mean is that more people understand the gist of spoken Welsh
Indeed, you are quite correct. Also (whisper it), Welsh will die for the some reason Irish has effectively died. You can't legislate it back to life but it will probably be more visible in its final decades than at any point before.
There won't be many political meetings in Porth where Welsh isn't spoken at all.
(In this little spat I tend to think both sides are being moronic.)
