Nope. They have varied interests just like everyone else. Don't forget, they're human beings too.
Autistic people are no more special than anyone else. Although savants tend to be Autistic, and Autism can give people advantages such as 'special interests' that allow Autistic people to quickly become experts in subjects or unique understandings...Autistic people are still just like anyone else.
Yes, autistic children like learning. Most children enjoy learning because it is what they are designed to do, to learn in order to develop and grow. Autistic children may enjoy learning more if learning about something that interests them, autistic people often have 'special interests' that they spend a lot of time and effort learning about and can become expert in.
Autism Spectrum Disorder is a neurological condition, autistic people are born autistic - we do not know why people are autistic.
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.
Autistic parents are advantageous to autistic children because they understand each other and can communicate with each other and share interests effectively.
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.
Often autistic people can spot autism in others, given symptoms of autism or that many autistic people are a little unusual - I'm autistic and have found over the years that we autistic people tend to be naturally drawn to each other, which is a nice thought. If you are seeking out other autistic people it is best to join an online autism community such as WrongPlanet - although like any other online community there can be a fair share of drama, most members are autistic so you can make friends with them online or look for other autistic people living close to you. Many areas have an autism group of some sort, for example where I live we have two autism social groups - try searching online for such groups, sites such as Meetup, and try finding local autism schools or groups to contact to ask if they know of any such groups suitable for you.
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.
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.
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.
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.
