We are Americans that believe in self rule, so why wouldn’t we support anyone wanting self rule for any reason?
Bu the Scots don’t need self-rule, as we already have it, with a Scottish Parliament at Edinburgh, and representation at Westminster. NI and Wales have assemblies and England dosent have a parliament of its own.
And we Scots JOINED the UK in 1707. That’s a huge point, we were not pressganged or conquered into it.
