Taking care to be precise in the meaning of words, and not clouded by political correctness, I do see that AS is a handicap for many people. It is not, however, a disability for most people. Defining a handicap as a condition that requires some form or degree of accommodation, AS manifests as a social handicap in a substantial majority of cases. Personally, my only meaningful relationships are few in number and are only with people that are tolerant of my many subtle differences. I can't just get on with people as the majority of non-spectrum people can. Because I am capable of working around this, I am not disabled; however, because I do need to be accommodated somewhat to develop meaningful interpersonal relationships, I can be considered to have a social handicap. A disabled person cannot bowl or play golf; in those games, a handicap is simply an accommodation made by adjusting scores to make the competition more meaningful.
Moving on from the linguistic pedantry into the deeper meaning, AS presents with social handicaps ranging from virtually none through very severe. While most of us learn to get by anyway, making the numerous little adaptations that we do even without thinking does absorb a significant amount of energy and we do tend to get run down and withdrawn at times. I suspect that all people experience this to some degree, but it tends to be more common and more severe among certain groups including spectrum people.
AS does come with an upside - the ability which many of us share to understand complex systems and to hyperfocus can be very useful for learning and performing complicated and difficult tasks, as well as thinking separately from the herd. While AS can be a very lonely existence at times, I wouldn't exchange it if it were possible - being someone other than yourself is MUCH worse.
