No, ALL -isms are about safety in numbers, or did you think is the purpose of groupthink is so you can cuddle over mutual interests?
But, by defintion, since Leftism seeks to overturn Rightism's ossified monolithic myopia, it's about free thinking - in theory, anyways.
The Right, on the other hand, finds such to be an obstruction to the proper order of things. Independent thinking is antithetical to the very essence of the Right, and irrelevant, as it seeks a retreat to what already has been. Not much thought required for staying the same.
But, alas, you may be on to something. As Leftism continues merrily on its path, it begins to coalesce, as there are eventual limits to radicalism and the 'message' gets distilled, gets given parameters, all the while natural Rightist (hierarchical) elements and tendencies settle in, hijacking 'the movement,' oink, oink.
In the meantime, Rightists realized Rightism is boring and subject to decay.
Enter New Gingrich's disruptive approach, seams split, walls shake, and the door is flung wide open for a rabble rousing populist to stir the listless hearts of the normally staid Rightists, reactionary elements take over and yadda yadda you see where this is going,,,
Yes, the Left has become a sort of Conservatism by fostering an increasingly purified vision and a decreasingly diffuse one, while the Right has become the new radicalism hellbent on destroying civilization in exchange for, um, uh, some elusive nothing. Because the fact is the base of both are just puppets and their respective porcine top brass fatten themselves off their minions' sweat, and so it goes till this barn burns,,,
