I also felt like whenever I posted there, no one read my posts; instead, they just skimmed for key words and then began a diatribe with their thoughts that were vaguely related.
The INTJs on this forum meet the descriptions (this one from personalitypage) "Others may falsely perceive the INTJ as being rigid and set in their ways. Nothing could be further from the truth, because the INTJ is committed to always finding the objective best strategy to implement their ideas."
INTJf reminds me of this quote (also there) "When Introverted iNtuition dominates the INTJ such that the other functions cannot serve their own purposes, we find the INTJ cutting off information that it needs to consider. If the psyche is presented with information that looks anything like something that Introverted iNtuition has processed in the past, it uses Extraverted Thinking to quickly reject that information. The psyche uses Extraverted Thinking to reject the ideas, rather than analyzing the information within its intuitive framework, and therefore reduces the likelihood that the framework will have to be reshaped and redefined."
