Old Krauthammer column explains current liberal hysteria

Resurgent:

...
... in a 2002 column: “To understand the workings of American politics, you have to understand this fundamental law: Conservatives think liberals are stupid. Liberals think conservatives are evil.”
...

Liberals make messes, we think, because they are incompetent infants. Conservatives, the long-suffering parents, must clean up the spilled Cheerios of millennia of Western civilization after every left-wing tantrum.

But the left holds a different perspective. While conservatives value reason and caution when making policy, liberals see this measured mission as morally wrong. They view society as a factory producing inequality and oppression, a system that deserves swift destruction. Out of the ashes they plan to build a fairer, more perfect union.

Who would oppose harmony, equality, and all the good things that liberals believe will result from their great cultural reconstruction? Only a villain, the left concludes.

Thus when conservatives seek to safeguard society as it stands, liberals accuse conservatives of every evil they can conceive – racism, sexism, homophobia, transphobia, or just general bigotry. Those who cling to the past must be moved aside in the name of the left’s better future – and if they will not move, they will be run over by the mob.

This explains the witch hunt of the "Russia scandal" as well as the intolerance and incivility exposed by the hostility to those working for Trump.   I have ridiculed this mindset with my own expression which calls for a resistance to the evils of liberalism.   It is an expression that really puzzles them because they think they are on the side of the angels against the conservative devils.

Left's ideological purity test is on displace in their reaction to Supreme Court decisions where liberal judges side with teh majority.
