The MMPI is very scary. I took that with my first therapist. I would think of it as helping your T get a better idea of your thinking, faster. It helps him see where his feelings about you were correct or incorrect and clarifies things.

As he said, he's not diagnosing you and saying that was good, goes along with his beautiful side of rebellion. If he were to have thrown up his hands and said, "Oh, no! You're borderline!" then I would have worried :-) There's always at least two sides to everything. I think he wants you to feel better/more comfortable and is hoping having a clearer idea of where you fall in the norms of zillions of people who have taken the MMPI will help you feel more "secure". It doesn't "mean" anything about you, it is just like saying you like your eggs scrambled with pepper, no salt. You can change what you like, how you behave and what you think and do, decide to grow in another direction, etc. at any time.

He thought you were more borderline than antisocial; that's a good thing. And antisocial is most often seen in young adults and gets better in middle age. It just means you don't like other people's rules and other people telling you what to do, don't like working in groups or socializing. Yes criminals often have antisocial personality disorder but the opposite isn't true that all people who are antisocial are criminals.

I think it is good to question, "is this wrong or am I just paranoid". Uncomfortable though. Hopefully your T will explain more and work to make you more comfortable with what worries you. It's good you sent him the fax.
