The basic tenants of liberalism are not, ironically, arrived at through deductive logic but through an arduous process of mental abstraction. What is presented to us by rationalists as a realist assessment of the world is in truth a vague conceptualization produced by a reductionist thought process. By abstracting thoroughly all essential properties from particulars it reduces them all objects in the world to mere mental concepts. These concepts are then presented to us as objective facts to be factored into account when it comes to socio-political organization. When reality negates these supposed facts the rationalist has no answer sufficient to negate reality.

Now, all this drivel would in a perfect world would dissipate in mid-air. Sadly for us, we live not in the perfect world but in the modern world, where it gets beamed into Middle-American ears by the fluorescence of Faux News. That it spills from the mouth of an adult convert to Mormonism who indulges in played up tears on air apparently puts no dent in its credibility.
