[3] Views vary with geography and culture, over time, and among individuals.
Many terms that some people view as harmful are not viewed as hurtful by others, and even where some people are hurt by certain terms, others may be hurt by the replacement of such terms with what they consider to be euphemisms (e.g., "differently abled" or "special needs").
Some people believe that terms should be avoided if they might hurt people; others hold the listener responsible for misinterpreting terms used without harmful intent.
[4] For some terms, the grammar structure of their use determine if they are harmful.
[8] On the other hand, there is also a grammar structure called identity-first language that construes disability as a function of social and political experiences occurring within a world designed largely for nondisabled people.
