Answer:
a social movement
Step-by-step explanation:
In the United States, people whose bodies do not conform to cultural ideals are often discriminated against. There are now a number of communities and organizations--such as Health at Any Size and NAAFA (National Association to Advance Fat Acceptance)--working to end discrimination based on weight. Sociologists would classify these groups as part of a social movement.
A social movement is a loosely organized but sustained campaign in support of a social goal, typically either the implementation or the prevention of a change in society’s structure, values or ideas.
