I wont say Ni is the polar opposit of autism, but it's close enough. People who don't know shit about autism should not throw out those lables so readily. They are only making themselves look like shitheads and encourage misinformation.
By that I'm illustrating what they mean when they say "knowledge is power" to the ones not knowing slapping a faulty label on something in order to devalue them is wielding power. Make sure that you always know the facts before backing down to someones criticism.
