My dad is an ENTJ. He taught me how to think analytically and he taught me humor of a dry sort. He is one of the more balanced people I know, but that probably has little to do with his being an NT. On the other hand, he does have a righteous judgmental side even though he doesn't express it directly much. I have my doubts about how much he understands and sympathizes with those less fortunate than himself, but he does try to help others in his benevolently patriarchal way.
He really is the only NT that I usually spend much time around. He is the only NT in my immediate family and I seem naturally drawn to other NFs. I have met some nice NTs before, but most of my experience of NTs comes from online communities. I love the intellectual debates of sites such as atheist forums which are filled with NTs. At the same time, I can only deal with NTs in large groups for very short periods of time.
