What are the best features, traits, or attributes about liberalism and conservatism?

In some circles being a liberal is a nasty thing. Other circles see conservatives as narrow-minded bigots. By the dictionary, I have not found that to be a description of conservatives. Those of you who are liberals, what are the best attributes of liberalism? And try to articulate what is better not simply because you want to point out how the other side isn’t. No one is on the political stump here. For those who are conservatives (we might have to look under every stone here), what are the best traits for being conservatives (same rules apply as did to the liberals)?
