Is there a fundamental difference in the "being" of a person with a disability and a person without a disability?

I have recently been reading Goffman's "Stigma" and Young's "Throwing Like a Girl," and often it occurs to me that many human attributes thought of as inherent are really just artificial barriers to equality.<br><br>I've been wondering, however, if some people with significant disabilities would always be inherently different from fully abled people.<br><br>For example, I have a friend who needs to eat every hour or two, lest he loses consciousness. Because of this, I think it's impossible for him to ever fully participate in society the same way I can. There will always be things he can't do, such as going on trips without access to food.<br><br>I work with a woman who has persistent and severe pain in her back. I think it's impossible for her to ever fully participate in society the same way I can. There will always be things she can't do, such as standing for more than 30 minutes.<br><br>However, I have friends of color and friends who are gay, and even though they face prejudice and obstacles that make it harder for them to participate in society, it seems like those obstacles are more artificial. As I understand it, it is a historical and cultural decision to make prejudice against those characteristics, to see them as burdens to the abled. <br><br>On the other hand, it feels like the state of needing to eat every hour or being in persistent pain aren't historical or cultural social decisions. It feels like those are more inherent characteristics. I know there is nothing inherently wrong with being disabled, but it feels like the kind of characteristics that I've described above are an inherent burden on the person with a disability.<br><br>Therefore, I am asking if there is some inherent difference in the "being" of people with disabilities and without disabilities? Not a moral difference, just a difference in the way they interact with the world.<br><br>TL;DR: I am asking if some people with disabilities would always be inherently different from abled people.
