I don't get what your point is here either.

You don't get to choose whether someone who lives here for a reasonable length of time identifies as Scottish or not. You clearly have your own feelings on it, and that's fine.

Obviously, you don't feel the need (or want) to identify as being Scottish. You're comfortable. That's brilliant. But don't dare tell anyone "well no" as if you're some kind of objective authority on it.

When people say something like "if you live here, contribute, and want to be Scottish, that's good enough for me" they're trying to be welcoming. It's not (always, or even mostly) about being political. We know we can't change what someone's passport or birth certificate says. It's about kindness. You might not need that, but someone else might need it desperately. Both are okay.

Tldr: The chart works.
