Just replying generally here, not to any specific comment. My Dad is an INTP - Totally beats to the sound of his own drum and was diagnosed with Aspergers too. He can seem detached and cold in the way he delivers information and I've never known him to have a single friend in his life (other than my brother and I). If I take the time to see the world through his eyes and not mine, I totally understand him and he certainly isn't sociopathic, he's a very kind, sweet natured man, but in his own way. If you don't know him, you won't know that his actions speak louder than his words - He never says 'I love you' - never, but he does show you... subtly, but it's there.
I suspect any of the personality types could potentially glean a sociopathic name tag given the right circumstances in childhood. I would imagine a fair few of them are extroverts too rather than introverts - though I'm sure that could be wrong - I'm not an expert. I say that because I've read that they often need a feed of attention, and an air of charm in order to manipulate. Although I hate saying 'they' we are all so different, even when we meet on the same or similar spectrums. We can't tar one another with the same brush. Are INTP's known to be manipulators do you think? I wouldn't know, I'm an INFP. No interest at all in manipulating anyone. I'm more, go forth and be yourself beings... leave me out of it lol, I've got my own little world to live in.
As someone else has already said... the thinking (I've most recently read, no idea if it's psychologically up to date) is that psychopaths are born and sociopaths are made.
There's an interesting debate online about whether Sherlock Homes (despite being fictional) was a Sociopath, the feeling is that he appears more like a man on the spectrum - Aspergers. So was Sherlock one of you chosen few too do you think? Maybe there's no such thing as Sociopathy or Aspergers and it's all one big spectrum that all of us possess elements of up to a greater or lesser degree? We humans do love to pidgeon hole and group information, admirable, but we do miss shades of grey.
