Inclusion means a wide range of things.
It can mean being ' accepted by other people', 'taking part in community life', 'able to lead an independent life'.
Or it can mean 'able to lead as normal a life as possible', 'included in the workplace', 'included in social/recreational activities' and 'offered the same opportunities as others'.
Unfortunately many people with autism are routinely excluded from society and prevented from undertaking these activities.
