I think both jihadi and far right youth are trying to find a sense of self in an indeterminate world. In such a quest, abandoning their views means the loss of selfhood, and that is unthinkable. Hence jihadi and far right youth refuse to compromise, negotiate, or settle. Often youth who become jihadis and far right advocates feel that they do not belong in the overall local, social narrative in which they find themselves and are searching for a cosmic sense of value. An excellent book is Reza Aslan, Beyond Fundamentalism: Confronting Religious Extremism in the Age of Globalization (Random House, 2010).
Thanks @Kirk Mac Gregor for your answer and good reference. I agree that anomie plays a big role here. It would be highly valuable to test a role of such (comparable) factors. Especially, because it may point to a subtle processes that contribute to actual transition into violence.
Hi Vanja, this may be a bit late for you, but there is a collection of articles on radicalisation and political violence in young persons by the Deutsches Jugendinstitut: https://www.dji.de/fileadmin/user_upload/bulletin/d_bull_d/bull109_d/DJI_1_15_Web.pdf

thank you. i am familiar with hogg' work. we used identity and perceived threat as conceptual standpoints. however, i wonder if there are any comparative empirical studies on these two 'types' of extremists. our findings shows some remarkable similarities with respect to motivations and triggers.
There is academic and grey literature on similarities between religious extemism and gang-related crime, if you execute a quick search. The findings of a University of Colorado Boulder study and that of the START consortium differ. Aside from the two I mentioned, I also found this: http://scholarcommons.usf.edu/cgi/viewcontent.cgi?article=1145&context=jss
