Sorry, krellin, but I think you're burning down straw-anarchists, and I also don't see how what you described about anarchists makes them sociopaths, either.
For one, there are two groups of anarchists, broadly speaking -- left-anarchists (the traditional understanding of anarchism) and right-anarchists (relatively new; they're the anarcho-capitalists mentioned earlier). Only left-anarchists oppose authority/hierarchy on principle; right-anarchists don't. Right-anarchists specifically oppose the existence of states, understood broadly to be involuntary hierarchical organizations that rely on the use of force to maintain themselves. I formerly identified as a right-anarchist and know some right-anarchists, and not a one seeks the dissolution of organized society. So while "disconnected from reality" might be a reasonable (if unduly harsh) descriptor of them, "sociopath" isn't.
And even within the left-anarchists, they still don't seek to dissolve organized society. I'm not nearly as acquainted with left-anarchists as I am right-anarchists, but most left-anarchists, as far as I understand, seek independence from the current political and economic system rather than to tear it down. You're far more likely to find left-anarchists trying to create their own self-contained places to live rather than resorting to violent overthrow of the system.
Certainly there are some left-anarchists (and right-anarchists, though it seems like this happens more with left-anarchists) who do support and seek to act out violent overthrow of the current political and economic system -- and depending on their means and motives they could well be considered sociopaths. I don't think anyone would argue that anarchists are by definition not sociopaths. But it's abjectly false to say that anarchists are necessarily sociopaths for opposing the current political and economic system.
In fact, your claim almost seems to amount to "If you do something to disrupt the fabric of the current societal system, you're a sociopath" -- which strikes me more as a smear of people who oppose that system than a serious description. After all, sociopaths don't simply oppose authority. They also have a notorious disregard for the rights of others, resort to violent means to obtain their ends, and display a lack of social and moral conscience. And again, while there are certainly some anarchists that fall under this descriptor, you'd be hard-pressed to describe all or even most anarchists this way.
