Some member of society who does not have a good level of understanding of autism can wrongly react with unfair intolerance and patience against their difficulties and ability. This can lead to intolerant attitudes and use this to attack their intelligence, character & integrity. This is without realising they have limitations on their abilities and coping mechanisms.
Other examples of mistreatments include deliberately exclude an autistic person from social, working environments and society.
Tips:
Set aside your personal ethics and principles when you see an autistic person beyond any perceptions.
The range of difficulties an autistic person is not the same so take time off to understand how it affects someone you know and understand and support their strengths as well
