You can basically divide people in to two broad categories.
People whose values are relatively hierarchical and individualistic, love guns, use logic and common sense and tend to be computer technicians, cops, mechanics, doctors, pilots etc.
People with more egalitarian and communitarian values, in contrast, resent individualism, base their life on feelings, ideas, hypothesis and theory. They avoid guns and tend to be interior decorators, bee keepers, lawyers etc.
People of the first group tend to be conservatives and libertarians and exhibit a strong allergic reaction to BS thus often been mistaken as "short fused".
People of the second group are immersed in BS and tend to be commie, pinko, liberals.
My unbiased opinion.
Good Lord, this is such an epic fail of statments and profiling that it does not deserve a reply.....
