It seems that society has this everlasting preoccupation with there being an enemy of some sort, a bogeyman really, without any real justification. Regardless of small or large group size, there's always got to be an enemy concocted or pointed out. Maybe it's a remnant of evolutionary psychology that people just can't seem to purge from their system. In the context of Aspergers, it seems that they are perpetually targeted as an "enemy" by a group, even if they don't pose any real threat (well, maybe a threat to the established social order, I guess ). Someone has to be ganged up on, and the others have to be brainwashed into perceiving or believing that this person is "the enemy".
On a macro level, it has been one country's citizens perceiving another's citizens as the enemy, or a minority group within their own country as the enemy. I don't see society as a whole shunning people on the autism spectrum as "the enemy", thankfully. This enemy labeling is more at the micro-to-medium level, like in controlled environments with a group.
But really, where the enemy labeling should start and end is with the criminal element. Hollywood has an obsession with criminals as the enemy because that's what sells, that's what society wants. I remember watching Scarface three times, and that famous line from Tony Montana: "You know why you need guys like me??! So you can point the finger at me and say, 'that's the bad guy'! !"
...but I guess that's not enough. You can't just have a fantasy enemy, you've got to have a real one, if that makes any sense.
Maybe one day, before I'm gone, I'll figure out society's obsession with enemies. That's the tragic irony with us Aspies - we don't look for a designated enemy, we somehow find ourselves on the other end of that obsession!!
