Ok but in real-world usage "nationalist = far right = nazis = bad". So I was clarifying that while that is not untrue, nobody is saying the Scottish independence movement or the SNP are that.
It might be regional or very US/UK specific. In many parts of the world nationalism is also associated with left wing separatist movements. For example, in Spain we have ETA[1], and in Turkey the PKK[2].
I've never specifically associated it with neither left nor right because in my country we have both right and left wing nationalist movements. Yes, far right nationalism is often fascism, nazism, jingoism, etc. but this isn't the only type of nationalism, and we don't use nationalism as a synonym for nazism/fascism, except when speaking specifically in the context of right wing nationalist groups.
