Sometimes it depends on why the autistic individual is unhappy. But it doesn't mean they are not happy at all. They can show happiness but not like how neurotypicals usually do. They know how to laugh and smile but not when other people do so.
It depends on the autistic person and whether they are accused of card-counting or similar. Many Autistic people are extremely intelligent in math. Not all, but most of them are. And casinos generally do not want customers to get rich so quickly so that would give them a reason to ban autistic people from casinos. Maybe it's true, maybe not, but it seems very likely.
Autism Spectrum Disorder is a neurological condition, autistic people are born autistic - we do not know why people are autistic.
Kids with autism can 'freak out' when other kids cry, all autistic people are different. Autistic people have lower levels of cogitative empathy, meaning that they may struggle to recognise emotions in others or acting appropriately in response compared to neurotypical people, however autistic people have significantly higher levels of affective or 'true' empathy compared to neurotypical people. This means that autistic people can be very sensitive to the emotions of others, when they are able to recognise others are upset it can make autistic people very upset too.
Firstly, it's offensive for you to imply that autistic people are abnormal - autistic people are different to neurotypical people, not less than. A person is born autistic, it is not something that happens to 'normal' people or something that you turn into, you are always autistic.
No, not all Autistic children are savants. Many Savants are Autistic, but most Autistic people are as normal as Neurotypical people with no particularly special talents.
No, not all autistic people lack a sense of humour. There is a saying in the autism community: once you've met one autistic person...you've met one autistic person. autistic people are as different and varied as neurotypical people.
Employers do hire Autistic people, however normally when they do they don't realize that the person is Autistic. There is a lot of prejudice against Autistic people so even in areas where there are discrimination laws in place Autistic people often cannot find work, Autistic people normally have to hide their Autism from employers to avoid facing discrimination.
No, not all autistic people act the same - autistic people are as different and varied as neurotypical people. Like with neurotypical people all autistic people will share common traits, but once you meet one autistic person then you've met one autistic person...we're all very different.
Your autistic child may not recognise their name as their name. Many autistic people are disconnected from how they are percieved by others, not all Autistic people accept the name given to them as representitive of them.
Autistic people don't 'get' autism, Autistic people are born Autistic just like people are born African-American or born male/female. Tony Hawk thus was born Autistic, he became Autistic while he was still developing in his mothers womb.
No, autistic people are not 'crazy'. Many autistic people can have mental health issues but they're no more likely to have mental health issues than anyone else and often mental health issues in autistic people is more to do with how society treats autistic people - e.g. depression is more likely in autistic people who are bullied or face discrimination.
Autistic people are as likely to experience auditory halucinations as neurotypical people. Auditory halucinations are not a characteristic of autism, if an autistic person is experiencing these symptoms it is a sign of a mental health problem and not due to their being autistic.
