Re: With all due respect to Gaelic speakers...
It's two words not one, with different meanings and pronunciation. The accent indicates pronunciation and the meaning is usually obvious from context. You don't have a problem with words like "watch" having several meanings, do you?
The article mentions two, but as far as I know, there aren't that many examples. Bàta (boat) and bata (stick) are the only ones I can think of (admittedly my command of Gaelic is limited)
I'm not aware of any organisation trying to stop Gaelic evolving. The acute accent dropped out of use in the 20th century, largely unchallenged. Bòrd na Gàidhlig is is only interested in the language surviving..
