Watching videos of kittens and puppies, I see that their play consists of mock fighting and chasing. During introductions, larger, older dogs are careful to not frighten kittens or puppies, often by keeping their elbows on the ground. Once they are acquainted, young animals attack each other with abandon, trying to prove that they could have killed if they had wanted to. Eventually, they will need to kill to survive, and really do need the practice.
Since humans need to fight socially for success, our mock attacks are verbal, and the attacker is best pleased if they get an interesting, fairly equal game out of it. Aspies run into trouble by over or under-reacting. We might make them look foolish, but that can backfire. We might just not know how to play the game, and so lose by default. There are better and worse ways to not engage, though. The situation to avoid is becoming an easy "point" for anyone in an "in group" to score by harassing you at any opportunity.
I have sometimes been able to defuse a situation with humour, and have seen others pretend to a major deafness, always misunderstanding and quickly "giving up." What other tactics have worked for you?
