They can feel free to disagree with me, however the fact is that Scotland is now an English speaking country as is many others, therefore lowland Scots is a form of English, in the past people in Scotland have spoken several languages, however English (again as in many other parts of the world) seems to have prevailed,

"some have made the point that RP English could just as well be called a dialect of Scots as the other way around."

interesting possibility !
