Is the term “Liberal” supposed to be derogatory in some way?

I love the word liberal cause the more I give out to others the more good comes back to me. Conservative is about holding back. I study properity & while you can save a lot that way I would rather prosper the Oprah way but giving to others & making the world a better place. So reps. are negative people & have all these things that are supposed to help them shame others but it doesn't work in 2009 it will take them about 5 years to notice this though cause they really have not noticed yet & I don't see it happening any time soon.
