Why is the puzzle piece symbol for autism?

The use of the puzzle piece as a symbol for autism is controversial and has been criticized for several reasons:

- It implies that autism is a puzzle to be solved, which can be seen as dehumanizing and othering. Autism is a spectrum of neurodevelopmental conditions, and it is not a puzzle to be solved. People with autism are individuals with unique strengths, challenges, and perspectives, and they should not be treated as objects of study or pity.

- It suggests that autism is a disease or a disorder that needs to be cured, which is not true. Autism is a natural neurotype, and it is not something that needs to be fixed or cured. People with autism can and do lead happy, fulfilling lives.

- It perpetuates the stigma associated with autism. The puzzle piece symbol reinforces the idea that autism is something to be feared or avoided, and it can make people with autism feel like they are outsiders or freaks.

Other symbols for autism that are gaining popularity include:

- The rainbow infinity symbol, which represents the diversity and acceptance of the autism spectrum

- The acceptance symbol, which is based on the American Sign Language (ASL) sign for "I love you"

- The red instead symbol, which stands for "real empowerment, diversity, understanding, and acceptance of all those affected by and associated with autism"

These symbols are more positive and inclusive than the puzzle piece, and they better represent the autism community.
