That is a weird distinction, probably is a cultural thing? How can be better to say one of the other?. I have more than 30 years with my twin brother. My aunt is a professional trainer for people with disabilitues (a sport, gold-winner kind of trainer), I have learn a bit of sign language and so on. But I never heard that kind of argument (ie: here in colombia none of both will sound more or less respectfull, are equivalent)
Yeah I read the article, and his rejection of 'people with autism' is akin to 'deaf culture' nonsense. Autism is a tragic, often crippling disorder and this guy wants it to be a culture. That's fine, he can feel however he wants and construct his identity however he feels best about himself. Calling a person 'it' is considerably worse, though, and that's what I was objecting to above.
