We would liken it to a religious belief in nonsense – say those who once derided, even shunned, anyone questioning the shape of the earth on which they lived. Or the cause of a disease or ailment. Or an eclipse of the sun – the moon.
You get the idea. Their game is their belief system – not the process of learning, observation and renewal. Yes, we sometimes question the apparent self serving nature of this group because we sometimes think they are too smart to not see the errors of their way so therefore we wonder – hey, they must be doing this to survive and sustain – think the Clinton foundation or the Obama library or some other monument to mediocrity or lower.
Here is a link to an article that asks the same question – why are the voices silent when they need to be anything but? It’s worth reading. Please go to: http://www.theatlantic.com/politics/archive/2015/02/why-obama-wont-talk-about-islamic-terrorism/385539/
Liberalism likens itself to the top of the Maslow pyramid. Enlightenment, etc. Until it starts to vigorously question itself – a very, very unlikely happening, it is just one more illustration of Santayana’s ever so true observation – “Those who cannot remember the past are condemned to repeat it.”
History constantly teaches us that those who cannot question themselves fail. Even though they accumulate a lot of material crap and vanity pandering along the way.
