Andy, my friend, you should know by now that reasoning with a liberal using the brutal truth and undeniable and irrefutable fact is tantamount to teaching the intricasies of quantum physics to a severe Down's Syndrome victim.
You're right. I would far rather spend my time explaining to an involuntary victim of mental incapacity the nature of photons than to explain to a willing adherent of Liberalism the nature of reality. A Down's Syndrome victim has at least a fleeting chance at comprehension; a Liberal, willfully blinded, has none.
