I was replying to you saying that it's better solely because it's easier to sing and that the lyrics to a national anthem don't matter. The best anthem in that context would be an instrumental one. Can't get easier to sing than that and if the lyrics don't matter why have any?
Since none of the nations of the UK have their own national anthem, the issue of replacing a centuries-old one doesn't apply in that context. But how would you feel about an English national anthem being chosen that was about one or more of the times Scotland invaded England and was defeated? Nothing about England, just about defeating Scotland. Would you approve of it on the basis that it had a good sound, easy lyrics and referenced an old military victory for Englishness points? Or would you apply very different standards?
No, you're saying lyrics don't matter as a strawman. I questioned your antagonistic emphasis on the lyrics of FoS when the official anthem for the UK has extremely poor lyrics for this day and age... which you agreed on but decided to spin into a claim of lyrics not mattering.
You're presenting it as equal value but the status of Scotland to England is such that a song celebrating a military victory over Scotland by England would have to overcome an enormous cringe factor since England has always been larger, more powerful and literally paid Scotland to join the current union after Scottish nobles went broke. There is no pride or honour in punching down.
The fact that Scots find connection to a time when there was a victory over England 700 years ago is not in perfect taste but it's a reasonable basis for their anthem since it reflects their low level resentment to this day from being the smaller neighbour and partner to England over hundreds of years.
That song wasn't imposed, it has recent public approval as the anthem for Scotland and while there are no official anthems this is the unofficial anthem.
GStQ had so much public approval ~300 years ago when the monarch had a lot more relevance that many other countries decided to have an anthem. But recently? It loses public votes where those votes get allowed.
Whether you like the lyrics or not doesn't really come into it if the people want it as their anthem to sing and represent them. Something which can be clearly said for FoS and not so much for GStQ.
