I truly appreciate your post...but I'll counter anyway (with absolutely no offense meant, just friendly discussion).
I wouldn't call it pandering to admit to a new type of disability that needs to be recognized and protected from discrimination.
dis·crim·i·nate
disˈkriməˌnāt/
verb
- recognize a distinction; differentiate.
- make an unjust or prejudicial distinction in the treatment of different categories of people or things, esp. on the grounds of race, sex, or age.
You are using definition 2.
You cannot legislate or demand an end to discrimination. It will never happen. Discrimination is actually a survival instinct, and people discriminate all the time, every day, with most decisions they make. People discriminate their foods (I really don't like the way that looks even though I've never eaten it). People discriminate their entertainment (I just hate <insert type> music even though I've never listened to that song). People will discriminate their social interactions (I can't stand being around rabid WoW players even though I've never played the game). Discrimination is a word for individual choice. You may not agree with the choices others make, but this is also a function of individual liberty. Freedom is sometimes ugly.
So, the question becomes what exactly are you discriminating against? With ADA (I won't even get into civil rights legislation) we have decided that there are certain forms of discrimination which should not be tolerated. Largely discrimination against
public access (not private mind you, boys only "clubs" are still legal for example) and discrimination against potential ability (he's disabled so there is no way he can be smart enough to be a lawyer, even though he has the certifications).
However, it is perfectly legal to discriminate when it comes to sex, age, religion, disability, etc., with employment practices in particular, if the case can be made that the person could not, due to their situation, fufill the role required by the work. So, this is why you don't see male waiters in hot pants at Hooters (to be silly about it). You will never see someone who has ALS playing in the NBA (or WNBA). Etc...and, guess what...it's perfectly legal (and it should be).
It is the evolution of social awareness.
Argumentum ad populum with trope. Metynymy. I doubt people weren't "aware" of conditions years before (as you go on to point out). They were quite aware. What it is, truly, is advancement in medical science which allows people who, 20 years ago, couldn't be treated, and therefore were treated to the best of the state of the art at the time (which required institutionalization in some cases), are now capable of living fuller lives.
20 years ago a prosthetic wouldn't allow a man to run (at least not fast or well). Drugs are now available to treat / control a variety of medical illnesses which 20 years ago would have rendered the patient largely incapable of daily interactions in any reliable sense. This is an advancement of medical science, not "social awareness".
Society has progressed to acknowledge the invisible disability as a "real" disability to be accomodated and not hidden and ostracized. That is why this "pandering" as you describe it occured. And I would remind you that before that the same process occured for the physically disabled as well. There was a time where physically and mentalally disabled individuals would be institutionalized and not accomodated as they are now. Is it pandering to those in wheelchairs to ensure ramp access to buildings? Because that didn't exist 50 years ago, but it does now.
Argumentum ad misericordiam and dicto simpliciter. You are setting up a straw man.
For example...however did our largely wheelchair bound PRESIDENT from 1932 until 1944 make it through life without ADA, I wonder? I'm quite sure FDR required "ramps" at some point.
Granted, FDR largely hid his infirmity from Polio from the general public, but if the point is "mobility"...well, he did just fine without ADA compliant ramps everywhere. Further, I grant he had means and stature to dictate things, but the man wasn't strolling onto stages on a regular basis, and he certainly did travel quite a bit.
My underlying point is, physical and mental disabilities are not "new"...and people were certainly well aware of it then as now. Medical treatment has advanced to allow them greater access than they had before. Your implication is that there was/is some massive popular discrimination against people with disabilities. This simply is not the case.
With respect to "accomodation"...There is a difference between "empowering" someone disabled and "excusing" someone who is disabled. A major difference.
You imply that one type of disability is more deserving of accomodations than another, which is flat out predjudice no matter how you spin it.
Yep...straw man. Everything you wrote built up to this point, which is really a fallacy.
Again, this is not a personal attack. Far from it. I found your post moving. I am extremely pleased that your son is able to interact with general society in a way that someone 20 years prior would not have been able to. I merely question the further implications and statements you made regarding the ultimate reasons WHY this is the case, and your conclusions.
Cheers!
