"The Butcher's Apron" is not a term that the Scottish self-determination movement invented. The British Empire with brutal and violent oppression colonized over 57 countries. None of the countries asked to be colonized and most of them had to resort to bloody and violent insurgency to drive the British out and gain their freedom/independence back.

To the majority of those colonized the Union Jack was known as the 'Butchers Apron'.
