That sounds plausible, too.

Various nationalism and other thinking, in different groups, at different times, are still largely a mystery to me. It seems relevant to group thinking we see today, which is still confusing (e.g., why is much of the thinking and dialogue around the two main US political parties doing what it's doing, and how is that representative/determining of what the broader population actually thinks).
