Yes, it is a habit, just like lying. I really enjoyed the previous article. My take is similar, I've always thought the difference between conservatives and liberals was like this:
Conservatives are basically pessismistic, always thinking that the world is going to hell in a handbasket; their worldview (and politics, etc.) is based on fear; and they are always looking to the past, yearning for some golden age that never really existed.
Liberals are basically optimistic, their worldview is based on hope rather than fear and they look forward to the future with pleasure, sometimes anticipating a future utopia that will never arrive, but usually seeing the world a little more realistically than that.

I have a favor to ask. I recently put up a blog, not to blog on, at least not for now, but as an information clearing house for a political project. If you have time to take a peek, let me know what you think and if you would like to get involved. I'm looking for an already well established online community to get this thing kick started and for maximum impact.
Thanks
