I don't think there is anything bad about being a cynic - just not a bitter one.

The bitter cynics are the ones that will roll their eyes or take a negative view of something you have said.
Others will listen to what you say, and even if they don't agree (being cynical) but smile cos even if they don't agree with your view or think you will 'suffer' for it will think it's lovely and know that you are genuinely one of the sweetest people around
