It seems worth mentioning that one might asume that "youth movements" (which is a bit of a misleading term I guess) are never about changing the world even though they usually proclaim it. They are always, from the outset on, about belonging and identity.
Even a small scene already displays all the dynamics of any social group and while believes and their expression may be more extreme in small groups than in large that can be attributed that in order to integrate a growing number of people a unifying ideology (using the term quite losely here) needs to become both straighter and less extreme.
In other news:
The romantic period tried very hard to construct a nationality from a broad, always changing and highly diverse culture and at least in my eyes, that attempt has failed.
Nationality is just another construct that lets us indentify and belong to some social group however abstract.
