The Stigma of 'Disorder'

I recently heard on the radio that the military with changing the name of Post Traumatic Stress Disorder to Post Traumatic Stress.    The idea is that by dropping the term "disorder' there will be less stigma associated with it and thus less resistance to getting treatment.  'This is not a disorder." One spokesperson said "It is a normal response to the trauma that men and women in combat may be exposed to."
I have no particular opposition to this.  After all, it's just a label and I'm all in favor of encouraging service members to get treatment - even if it's just preventive- and I'm certainly in favor of reducing the stigma associated with Post traumatic stress. (disorder)  At the same time, I think this is indicative of how we deal with stigma.   I wonder if we are going at this ass backwards.   If 'disorder' is seen as a stigmatizing, negative term, does anyone with a medical condition really 'deserve' to have the label 'disorder'?    None of us like a stigma whether we are soldiers or not.   I imagine that next we are going to stop referring to Autism Spectrum Disorder and just call it 'Autism Spectrum.'  Bipolar, obsessive compulsive, anxiety, will all follow up with a name tweak. 

 Along the same note, it is frequently and loudly stated that "AUTISM IS NOT A MENTAL ILLNESS!!!"  When I look up the definition of mental illness - there are several but most of them say pretty much the same thing.  It comes down to impairment of cognitive, emotional or behavioral functioning.  How is autism not a mental illness?     I can hear someone responding already "Autism is a neuro-developmental disorder."  Yes, but many mental illnesses are also neuro-developmental disorders. Child onset schizophrenia for one.  Maybe the objective should be de-stigmatizing 'mental illness' period.  We could give it another name, but the real objective should be fostering an understanding that people with mental illness should not be shunned or shamed any more than someone in a wheelchair should be.  They are not a danger to society and with the right accommodations and/or treatment can lead productive fulfilling lives.
I've seen parents get angry when their child is referred to as 'disabled' and then get upset when their child is denied services intended for the 'disabled'.  'We'd like the services but not the stigma please.'  Here's the deal: All of our children deserve services without stigma.  You kid isn't any more deserving than another.
Yes, we can drop the term 'disorder.'  But is that really going to have the impact that we are hoping for?  By dropping a term used for one group to distance themselves from another aren't we making it clear that we should judge and stigmatize certain groups of people but not others?  Soldiers that have post traumatic stress should never be blamed for their condition.  It is a natural response to trauma.   However, no one with a health condition should be blamed for it.  It is a natural response to our environment and our genetics.
