So while it's perfectly normal to notice differences between groups, it's not normal or reasonable to assume that everyone in x demographic possesses y negative trait. This is the kind of crap you get from dumb INTJs.
NTs are good at one particular kind of intelligence; that is, the NT kind. Your view marginalizes other forms of intelligence (such as sensory/tactile or emotional intelligence) as meaningless, which is not the case.
Although, it does fit conveniently into your INTJ-supremacist worldview, so carry on.
Even other INTJs in this thread are calling you out on this. It's ironic because you fit the conspiracy theory nut stereotype so well:
--Believe that non-NT forms of intelligence aren't real intelligence
--Have a lot more in common with Dale Gribble than you realize.
