Yeah I agree with Pandoren on that one. I don't think using NT is offensive. It's less offensive to those of us on the spectrum than calling them 'normal'. NT is a very literal description, they have typical neurology, that's hardly any more of an insult than us saying they have green eyes.

Again, the word doesn't make it offensive, it's down to usage. If people on the spectrum use the term to belittle somebody, that doesn't make the word offensive, it makes the people using it offensive.
