personality type leads to political affiliation leads to behavior as a group
think the best way to conceptualize it is "warriors" vs "shamans" or "philosophers"
warriors are self-reliant, show their aggression openly and directly, draw power and influence from personal strenght, more individualistic, less neurotic, less indiscriminately cooperative. rightwingers tend more towards this type.
intellectuals are less mentally stable (studies showed high IQ correlating with mental illnesses until they differentiated between high IQ in business and high IQ in academia. only in the later did the correlation hold), their aggression is social in nature, blaming, shaming, gaslighting, gossip etc (more feminine men, more female typical strategies and behaviors), they draw power and influence through influence over others, meaning they get their way by occupying a high position in society, so they rely on and desperately seek social status, they are more collectivist and cooperate more opportunistically.
you can see this split in almost everything, even in the prefered choice of physical activity. rightwingers go weightlifting. higher society lefties go running. rightwing politicans care about their career, leftwing politicians are true believers that care about the cause.
turns out, in a battle of group interests you don't want to be part of the group made out of independent individualists.
interdependence creates loyality and without loyality cooperation breaks down in the long term.
since those are mostly innate (genetic) predispositions, you can't make right wingers into leftists. you would have a better chance trying to subvert leftists by using their own tendencies against them, by playing their game by their rules. incels are more marginalised than all the groups leftists are championing, so there is at least a theoretical path to victory on that route.
rightwingers will en large stop being on your side or giving a fuck about you the second they themselfs are no longer affected (individualists, remember?). how many would still be invested in incels as a group if they got a girlfriend tomorrow? how many would still care enough to invest time and effort and money and accept personal risk for the cause? some few might, but as a group rightwingers won't care enough.
