Or at least they think they do. Usually it's about how to run somebody else's life.
Allow me to clarify my statement: I meant to say the party apparatus and the politicians are essentially members of the same Ruling Party. They just kinda-sorta swap power every once in awhile, but they're always there. They exploit those honest policy disagreements that we regular joes have to get us to join their team and demonize the other guys.
I honestly think that too many opinions are emotionally held rather than rationally arrived at. I think that's why people get so upset when their beliefs are challenged: they're not sure why they believe what they do, they just feel that it's right, and so any disagreement is viewed as a personal attack. It also leads to the aforementioned demonization: I think what I believe makes me a good person, so if you disagree with me, you must be a bad person. Nevermind what the arguments are, what the logic is, we skip on by that and assign the motivation solely to character, or lack thereof. It's utter nonsense, and yet I'm convinced that describes a majority of people. Sadly, that is also exploited by policitians, even those who claim to be outsiders.
