Dealing with "different" students

I feel that my lifestyle is much different than everyone else's. By that, I mean that my way of thinking, my way of being open minded and accepting is much different than some of my peers. I've often noticed that some of my friends just shut down around people with disorders they aren't used to. There are a few students in the school of music who do have disorders like Aspergers, ranging from very high functioning, to somewhat low functioning. And I've noticed that when a certain student with this disorder comes around my friends avert their eyes, pretend like they don't know he's there and just outright ignore him. I find it sickening. 

I don't understand how my peers, being education majors, don't know how to deal with people who are different from them. There is a possibility that they will have students with social, mental, and physical disorders in their music classes. Its not as likely as the main-stream subject, but I have been in classes in high school with a boy who is living with Down Syndrome, a girl in a wheelchair because of a spinal disease, and now in college 2-4 of my peers have Aspergers of different functioning levels. For me, its just normal to interact with them. But, I think I was lucky enough to be brought up around these disorders. My mother is an extremely wonderful woman. She has worked her way from physical ed/health teacher while also teaching special education, and is now the head of the child study team at one of the three high schools in my town. I think she may actually be one of the heads in the district as well since she deals with students from all over the district that go to different schools. She used to bring me in for "take your daughter to work day." She also used to organize rides and outfits/dresses for prom so her students could go to them. So I was around and exposed to these kinds of disorders from a young age. And even in my childhood, I was never exposed to something like what is in this video. 

I post this video as a question to my peers. How do you think you would handle something like this in your classroom? This is much different than a mental disorder, and I'm curious to see how my peers would handle something like this if they have trouble with simple conversation between themselves and someone with very high functioning Aspergers.
