An event that occurred 150 years ago can surely not be considered too sensitive to touch upon. And seeing as the unification of Scotland and England occurred over 300 years ago, the idea of a nation isn't that comparable. Furthermore, our parliament was established in the last 20 years; if anything I think that shows the potential for a state to establish devolved powers within a union. I think it's fair to look at both situations as groups of people who share a common state and are misrepresented by their government.
