My problem with that kind of a worldview is that you're identifying more with being racially Scottish than anything else.
I'm not harming anyone. It's not to the detriment of people who are not "ethnically Scottish", such as my mother who is not "ethnically" Scottish at all and actually grew up in London, or the people who came over from Belfast at the turn of the century and gave me my surname, or the English gardener from Bedfordshire whose progeny included my Grandmother, or my English Uncle, raised in Middlesex, who plans to vote Yes in the referendum.
I have notions of "nation" that generally transcend blood, it's all about "heritage". It has less to do with genetic continuity than cultural continuity.
Culturally, you're much more similar to a Roman than an ancient Scot (if they're called that, not sure).
That's true, though that's more for the sake of convenience than anything else. We know so little about the ancient Scots that it's hard to model ourselves on them. That hasn't stopped me trying to learn our indigenous languages and be closer to our ancestors. If it didn't cause problems professionally, I would actually take off my shirt and paint my body with various designs. I have considered doing that at home but copper ore in a muddy form is hard to come by these days and it would stain the couches.
But indeed, they weren't called Scots back then, nor were we one people. My ancestors actually fought the Scots and Picts. I'm just referring to the peoples that lived on this landmass back then collectively.
I can stomach cultural nationalism, where a significantly different culture may wish for an independent government, but basing it off of ancestry or whatever notions of race we still have rings alarm bells like crazy.
What I'm talking about shouldn't ring your alarm bells though. I'm not advocating that we ethnically cleanse English people or something. I'd just rather we washed away Imperial yoke and found confidence in our own heritage and history, moving away from the cultural cringe that plagues us.
Not that this point necessarily has any relevance to the modern movement for Scottish independence, but I would still intensely disagree with removing traces of latin in Scotland.
Take it as an issue of breaking free from the shackles of ancient Imperialism, good sir.
