Liberals don’t.
They have the most massive blind spots I have ever seen.
Liberals think that because they drink free trade coffee or donate to the WWF that it is ok to drive drunk or shop lift or, as is a recent case, outright kill someone.
They have elevated themselves to "righteous" and that means everything they do is good by definition.
The rest of us are "evil" and so their setting us up to be murdered is by definition "good".
By contrast their not having everyone falling down and worshiping their wonderfulness is a sign that they are being harassed. And no one in the whole history of the world has ever suffered they way they do.
To put it very bluntly, you are seeing the sin of pride in full flower in them. Nothing is good if it gives them a moment of discomfort, nothing is bad if it gives them a moment of pleasure.
A toddler in a full meltdown has nothing on them. Because a toddler will grow up. They never will.
