If you have Ne anywhere among those four functions, your Intuition is projected outwards and your Senses are projected inwards. Ne-users like to talk over and deliberate plans of action before confirming final execution.
Ni is often very intolerant of any external ideas that do not fall within its inner vision. It doesn't discuss theories it won't immediately implement, it doesn't show its inner complexity -- it shows its Senses (Se) to give an appearance of strength and a continued progression upwards, while the inner "theory" behind it all remains shelled to the world.
Read: shelled intuition.
Rule of thumb, whenever an MBTI source makes a statement about specific MBTI types that contradicts the roles of the Cognitive Functions, they're wrong.
On another note, it seems a bit petty and unbecoming for a self-proclaimed ENTJ to victimize himself, saying he feels "alone" in a world of people who share his dominant function but not his auxiliary.
