Maybe I'm wrong, maybe the Kilt isn't 'just clothes'.

Many of the clans of Scotland are of Scoto-Norman origin.

From Wikipedia.
The term Scoto-Norman (also Scotto-Norman, Franco-Scottish or Franco-Gaelic) is used to described people, families, institutions and archaeological artifacts that are partly Scottish (in some sense) and partly Norman (in some sense). It is used to refer to people or things of Norman, Anglo-Norman, French or even Flemish or Breton origin, but are associated with Scotland in the Middle Ages. It is also used for any of these things when they exhibit syncretism between French or Anglo-French culture on the one hand, and Gaelic culture on the other.
For instance, the Kings of Scotland between the reign of David I and the Stewart period are often described as Scoto-Norman. A classic case of Gaelic and French cultural syncretism would be Lochlann, Lord of Galloway, who used both a Gaelic (Lochlann) and French name (Roland), and kept followers of both languages. Another example of a Scoto-Norman, would be Robert the Bruce, who had a dual Norman-Gaelic heritage.
Over time, several lowland clans intermarried with Normans who moved north, introducing Teutonic (Germanic) Norman family traditions and social structures into the native Gaelic traditions.[citation needed]
The term is used by historians as an alternative to Anglo-Norman when that term pertains to Scotland.

One of the major clans up here in Caithness, Scotland are the Sinclairs which are one of the Scoto-Norman clans.

Some local Scots I know will not admit or do not even know of their Norman origins.

It should also be noted that the Normans are of Viking origin.

Its such a total mixup that depending how far back you want to go, drawing a line as to who exactly is Scots becomes impossible.

So English Bloke, I am quite sure you have every right to wear a kilt wherever and whenever you want and I bet the guy who confronted you did not know his true history.
