Political
I would consider "radical discontent" to be an attitude. Attitudes originate from the interplay of perceptions of the environment and criteria for judging the environment. But why should any of these two be influenced depending on the "psychology of discontent" as discussed?<br> Isn't it more plausible that the "psychology of discontent" determines the means radically discontent citizens choose in reaction to their radical discontent? (Based on how I would conceptualize radical discontent I would thus also disagree with the statement that " radical discontent is characterized by verbal or physical aggression"). In this vein, many of your elaborations further below indeed concern the choice of tactics among dominance-oriented individuals (and not disaffection as an attitude). Also, most of the empirical evidence you cite (and that you generate) seem to investigate particular behaviors and tactics. Altogether, if I understand you correctly then your theoretical proposition is that dominance-based orientations fuels radical discontent (eg, p. 4, 13) but wouldn't it be more in line with your argument to (only) posit that radical forms of activism follow from dominance-based strategies? (In the empirical analysis, extreme discontent is then also not the dependent variable). In other words, it is not so much about radical discontent as an attitude but about radical political behavior?
This adjustment takes nothing away from the study and - with an eye on your empirical sections - it is likely what you have had in mind anyways. I was just thinking about these questions while reading the paper.
