If a person believes X, they must also believe Y...
Folks get the idea of what a "liberal" looks like from what the media feeds to them, and when a person has ideas that don't fit your personal stereotype, the person gets accused of being messed up?! If you find yourself accusing someone of not fitting your image of what they should be, maybe it's your image of them that isn't accurate. Maybe you should be asking yourself where that image came from, and whether there are facts to support it.

Greg, you made a generalization about gun owners and said Mick "can't prove the statement universally untrue by citing a single exception." Would you care to offer proof that your generalization is true?

If you're arguing with Mick because he doesn't believe what you think he should believe, maybe your stereotype really doesn't fit everybody you think it ought to.

...and I'm another "exception."
