cstross isn't Scottish though he lives in Edinburgh, but I think he's Northern English so the same general principle applies:

Being a Scottish Tory is like being an African-American Republican. Even if you agree with some or most of their stated policies, you're all too aware of the fact that in reality they've been waging class-warfare against you, your family and neighbors for decades and that often the libertarian (or otherwise) economic theories are just convenient masks for the worst kind of nepotistic crony capitalism, and that wide support for their polices is gained via populist xenophobia.
