A strange word to take offence to.
To me, settlers will always mean White Settlers, directed at the English who have a tendency to try and take over any community they decide to settle down in.
Nothing like an English voice on a committee teling you what you're doing wrong.
I wonder if they'll happily go home when Scottish independence means they are an immigrant in a country they used to be in a union with?
Not that I'm advocating repatriation you understand, just wonder if they could ever see themselves as immigrants.
