I don't think Asperper's people don't have empathy. They might not respond appropriately as neurotypical people, but this doesn't mean they don't have empathy. However, I think it's true that men with Asperger's suffer romantically, because women value the emotional response by nature, which might not be found as they expect. But the question is then: what should they do? Describing them as cold and ostracizing them because of that obviously make them feel bad and doesn't help. Do they still deserve love and intimacy and physical affection as any other human being? or they are destined to be alone and they have to accept it as a fact?
