What ever happend to "We are all one people"?

Hello people,

I have been noticing and studying things that have one group or another treated unequally. Mainly is people with disabilities. Sure they have the Americans with Disabilities Act (ADA) to make sure that all public places are accessible, but they are able to make it be like when the Black's and White's had different doors. Sure these doors don't have a sign saying Disabled people only, but it makes it pretty clear when there is a step in front of one door.

Then when people with disabilities don't have services, such as being assisted to bed, in the community they are forced to leave their homes and go live in a Nursing Home with a bunch of strangers. Sure this is in order to make sure that they can live, but how would you like it to be forced to live with a bunch of random strangers because you couldn't change your clothes by yourself.

In this day and age you would think that everyone should be treated the same. I mean after all we all are "one people on this earth." We aren't split into "Perfect" people and others.

I have to wonder why do people consider those that don't look or act exactly the same as "freaks"? It just makes no sense.
