Well, the trouble with our liberal friends is not that they’re ignorant; it’s just that they know so much that isn’t so.

Exactly.
In order to understand them, you have to understand their motivations.
Your standard sheeperal clings to the lie of “I’m a good person” or “I’m a superior person”. Everything they believe, support, and do is with the goal of affirming this lie. They are not interested in examining an issue beyond the point where this goal is satisfied.
Any discussion of how the policy/issue/person they support is not “good” is taken as a personal attack, because it strikes at their sense of goodness or superiority.
This is why it is so difficult to discuss issues with sheeperals. You think you’re discussing the best policy to accomplish a stated goal. They feel attacked when you deride their pet policy.
