I’m not sure it matters. The people who mistakenly link the name with the KKK would be wrong.
The Scottish clans predate the band of slack-jawed, racist, inbred rednecks by more than a thousand years. I think that gives them ownership of the term ‘clansman’. On top of which, if someone does make an incorrect assumption and asks their barkeeper about the origin of the name, it makes a good talking point.
