The "non-voting" part is hard to understand. Do you really not care whether Kerry or Bush is elected?
This is a hard one to understand for most folks, but here goes: I view all adult humans as sovereign individuals. They may empower an agent (politician) to exert dominion over thier own lives and property, but it is immoral to appoint an agent to exert dominion over a third party.

So much of our lives is politicized. This gets people riled because collective action through the state is predicated on initiating violence, somthing most folks reject as individuals, but embrace as a collective/mob.
I see one guy saying "I'll send men with guns to effect X", and another saying "I'll send men with guns to effect Y". It is not so much the policies I object to, but the means.
