Yes, you have every right to be disgusted by the NTs collectively, and I feel you should be free to speak your mind.
There is indeed a contingency of people here who are quick to say "not all NTs are that way, maybe you should examine yourself, my best friend is NT and he's not like that," etc. etc., which sort of ignores the fact that it's a criticism of NT behavior collectively, not individually.
But collectively, yes, you should call the NTs out on their behavior. Someone once told me that the reason so many with Asperger's are quick to defend the NTs is because they secretly wish that they can become NT...or at the very least that NT society will magically accept them one day, even though that's not going to happen. It was a good theory and may explain such behavior.
