"Othering" differently abled people

I was very interested in our discussion today when someone brought up the topic of what really is the "other" and who decided where to draw the line as the "other". I feel like a lot of times society misses the point that we are really the "others". None of us are the same and yes, maybe two people are "normal" because they both do not have a mental disability, but the lives of the two people are completely different on so many levels. No two people have the exact same capabilities and therefore every person is disabled in some way. It seems like society has just decided to marginalize people whose disabilities are either more extreme/noticeable or rare, which puts some people at a major disadvantage from birth. This marginalization not only puts people with disability at a disadvantage, but also society in general because in my opinion, they don't get to experience the joy and kindness many of the differently abled people bring to the world. For example, one girl at my school with a mental disability was the sweetest person in my high school, she just searched for ways to make people happy and smile. Luckily for some of my friends and me, we were able to experience her genuine heart and ability to make people laugh. Other people who categorized her as the "other" did not get to experience this or get to know her and they were missing out on a person who could make you smile no matter how bad your day was. She ended up winning the school superlative of "Day Brightener" and some people realized they really did wish they had gotten to know her. People need to realize that we all have disabilities and therefore should accept each other no matter how different we all are.
