Deleted my last response because I hated the wording.
Clubs, to me, are a bad idea, because they promote exclusion just as much as they promote inclusion. For example, say there was a club for people who loved the colour orange, and they were holding parties with free cake, but you could only join if you liked the colour orange. If you didn't, the club wouldn't let you join in and eat the cake, and you'd feel excluded all because you don't like orange, but want some cake.
Not saying that the AS club you want to start would hold parties with free food, but it just comes across as purposely alienating yourself from the rest of the school by excluding them from your activities. Also, if you wanted to do some kind of social skills thing, it'd be better to get a school counsellor or psychologist on board as they'd know exactly what to do.
