I have a theory about how to define a liberal. Point 4 is that liberals are always in favor of killing innocent people. If one always keeps that in mind one can always understand why this story and other similar stories are reported as this one is. Liberals love mass killers, and are always opposed to the death penalty, because usually, murderers will kill innocent people again. That also explains why they love communism and abortion. Liberals are always in favor of “gun control,” because that make killing innocent people much more difficult.
As far as truth, I think some liberals know what it is, but they always deny truth. Truth is very much too inconvenient, and leads to too much self-control.
I think you have a good system going. Call it “The Constants of Liberalism.” No matter what the subject if it is liberal in origin those contants will be represented in some way or another. We can take your Point 4 and see it here in gun-control, in abortion, in euthanasia or in the liberal position on the WOT. It fits in welfare, taxation, centralized control and “separation of church and state.” Some dimension of Point 4 can be seen in all of those positions. Even the fear and disdain for the truth is rooted in protecting the personality not life.
