Many people who know me consider me to be "left" but it makes sense to me. The Internet is just a medium. It doesn't favor any particular viewpoint. There's this idea from summer movies that the "good guys" are always hip with the new tools. That's not true. If anything, it does tend to be the underdogs or insurgents that are the early adopters, but this status has nothing to do with "good/bad" or with any particular political affiliation.
Unfortunately, the "explanation" feature is not built into the sockpuppet software yet, it is still in alpha, but I am sure in a 6-9 month period you will be able to get some kind of vague generic explanation.
