This reveals another aspect of the liberal personality: their insufferable conviction that they are the very embodiment of reason and intellect.
You know, those goofy "folks" at the dinner table look to you as the voice of reason on the subject....so how 'bout you just walk their dumb asses through it? These are simple flyover folk, they probably drive domestic cars, so they could use a bit of handholding. You'll get to dazzle these provincial proles with your superior liberal intellect and your cultivated, urbane sensibility. This will probably be good for months of mental-masturbation material, as you fondly reflect back on the moment you opened up a can of reasonableness on those rube relatives of yours.
