Hmmm... lets see... I didn't say everyone needs to be the same, and there's a big difference between considering "being different" a dissability, and considering "not being able to do something" as being a dissability.
In regards to history, are you referring to the invention of the wheel chair and prosthetic limbs, or hearing aids, or maybe asthma inhalers, or perhaps insulin or pace makers. Wait a minute?!? Are those people just conformists! Wow they tricked me!!! I thought they just wanted to live!
I think it's laughable that people are as against having their hearing fixed as I would be against having my hearing taken away.
