D.P.
I think I understand where you are coming from. Years back, when no O. was aware of things like ADHD, AS, etc you had a society that had "those people" that were considered "off" or "slow" their whole lives. Many never reached their full potential. I'll bet a lot of us who are adults today, can relate, as I can, to a peer, coworker, etc who clearly exhibits Aspergers (we have an IT guy who completely fits that, but he knows his stuff, does a good job,etc) or the like and it must hav been through extreme perseverance that they have achieved what they have so I know we can all agree that dx is a GOOD thing when it benefits the individual.
BUT (and I may get flack for this--that's OK) I do think that parents are HYPER sensitive to any quirky behavior exhibited in their child and are very quick to jump on the ADHD/AS bandwagon.
IMO, all kids have "issues" some more severe than others and NO kid fits the "typical" label perfectly.
I'm always blown away by the moms of infants & toddlers that freak out because their child doesn't "show enough eye contact" or "lines his little cars up in a row" and are panicky about autism.
I feel that society, as a whole, has the mentality of wanting a magic pill...if this happens, give them this and ALL BETTER which we all know is not the case in reality. So, yes, I see what you are getting at.
I think it's part of a larger trend in this society to "put a label on it" be it typical or autistic, conservative or liberal, etc.....
