What?

First of all, autism by definition means you have below average IQ.

Second, people on the spectrum aren't 'devoid of emotion and empathy'.

This seems like a sarcastic jab at people with autism, somehow. If it is not, I guess you have no idea.

People on the spectrum have difficulties connecting with other people because they are often not appealing as friends.

If another person isn't able to make you feel good about yourself, there is no point. You can respect that person's intellect or objectiveness, or logic, or depend on their loyalty or non-judgment, but that leaves everyone completely cold.
There is as difference between having a nice personality and having an appealing personality.

Think of it this way. Why do you fall in love with that one specific person, and not with everyone else that has similar qualities? Having autism is like having the trait that makes people very rarely feel that way about you.

There is a reason why autism is such a strong insult. There is a reason people like to laugh at Sheldon on the Big Bang theory. Yes, people with autism are fine. Just not as friends and definitely not as romantic interests. Unless maybe they are really good looking and high functioning.
