Heresy
He's right in that there's a very important and popular Zeitgeist here in the U.S. where person A and person B can say a particular fact P, and depending on certain external physical visual characteristics of person A or B (how the light bounces off of them or refracts), P can be taken to be false, or evidence of heresy.  And what is interesting is even just raising the above objection in purely logical terms, is enough to have the dark shadow of suspicion cast upon thee.<p>Let's hope the liberal values prevail, and we return to our search for truth, which does exist.
