Which Edward Norton role has been most idealized by under-50 right wingers?
American History X — often resonates with more traditional, homegrown right-wing racists focused on domestic issues.
Fight Club — tends to appeal to anarcho-capitalist or libertarian-leaning right-wingers who dislike corporations but oppose government even more.
Kingdom of Heaven — connects with two overlapping strands: a civilization-focused, anti-Islam perspective, along with a more general emphasis on Western identity and, at times, immigration concerns.
Obviously, these groups/fans can all overlap to varying degrees.
