There is constant reference to "Gaels" by BBC, Scottish Parliament, An Comumn, Royal National Mod, the Scottish tabloids etc. but nobody ever defines the word. I think, not to do so, is most convenient to many. I do think that it needs defining when it is used as if referring to a group of people like the Scots or English.
Going by previous submissions to this thread, there are two types of gaels; Those who settled on these shores from Ireland and the current undefined version.
To be fair on CLI, I'm sure that their reason for using the term, New Gael, is an honest attempt to say to people that they are welcolme to learn the language and culture and become a Gael.
All broadminded Scots welcome people who come to this country to learn and contribute to our community. They are, and should be, considdered fellow Scots. I think Padraig at CLI is using the same reasoning as regards to being a Gael.
