The attitude Daniel refers to comes from a level of unawareness and being uneducated about the topic of persons who have disabilities. Being uneducated, people tend to become superstitious and may believe in mythical stories/folktales in which can result in discrimination.

In my experience, a disable child was accepted into one of the school I previously worked. In the beginning, he interacted by himself most of the time. The other students observe the disable child behaviour. Some was afraid to go next to the child.  The teacher made the disable child feel safe and welcome in the school's environment. The staff members also educate the other students about being different/special until sooner than we expected everyone eventually started looking out/after the disable child. The children helped him when needed, played with him and made him one of their friend.
