LOL! How old do you think I am? Do you realize that I'm 50? I mean, I know I LOOK 25, but in truth ... *smile*
I don't think that news people, and scientists, and artists, and educators do what they do because they believe they can change things. I suppose some of them may when they're young, but like all of us, as they get older, they will discover just how small and insignificant they really are. But I think they do understand that change itself is inevitable, and that perhaps they can play a part in how things change. I think liberals have a lot of faith in God, and humanity, and in themselves, and so are not afraid to embrace new ideas, new discoveries, and new ways of doing things.
I think conservative are mostly motivated by fear, and by resentment. I don't think they trust in God, other people, or themselves. And most of all, they hate change. They want to maintain the status quo at all cost. And this is why most rich people are conservatives. They've got what they wanted, and now they want to keep it. That's why they're all about law and order, and having the biggest guns, and owning the politicians, so that they can control the will of society. It's their own society that they most fear, because they believe that everyone else is as shallow and greedy as they are, and will rise up and take what they've got if they don't keep a close reign on everything.
