Think of verbal confrontation like pro boxing. NT's are natural pros (generally speaking, of course) and AS's are just Joes (and Joannes) off-the-street.
Being a regular Joanne, it would be natural for you to want to flee if you suddenly saw yourself in the ring with a pro; but maybe your friend is also a pro (i.e. an NT) and thus they would have a better chance. So, with that, why not tell your friend that someone is trying to beat up on you? Makes sense to me.
On a side note, I think Aspies can be very stubborn and convince themeselves they are correct; not to be decietful, but because we usually say what we know and know what we say --we're just sometimes wrong, unfortunately. SO, using my example above, if this were WWF wrestling, we would be, say, someone called The Brick Wall. This guy would never have to fight, he would just defeat his enimies by standing there and letting them exhaust themselves... think about it.
