PS:
I would also help them to distinguish between games and real fights, and to understand that loyalty towards one's own team does not mean hatred of opponents. NT sports fans ofen see their own teams as good and the opponents as enemies, insulting them without consideration of their merit as sportmen.
Children will play games in which they will be taught to be sportsmanlike and to have respect for the skills of opponents and to show due admiration.
In fact, I would get other people who suffer from the same syndrome to teach this, I would not leave the training solely to Aspies, because I feel that they should learn to help themselves and others within their neurotype. Many of them who are involved in one-to-one competitive sports such as martial arts have an advanced understanding of respect for opponents, and even though their sport involves fighting, it is not fighting due to enmity. These people will lecture to sportsmen and fans of team sports such as rugby and soccer and encourage them to watch match replays in which they can see how good some of the opposing teams are.
They will have to learn to project their feelings: "Just as you are happy when your team wins because they represent your community/country/whatever, so the other guys are also happy when their team wins. Therefore, if your team does not win, you need not be sad, because you can see how happy the other people are, and rejoice with them in your heart, and congratulate them. Also, your team can learn some tactics which they can apply next time."
They will also learn to distinguish between sporting prowess and goodness as a human being, so that they do not automatically make role-models of people simply because they are famous for sporting achievements.
