I understand that your comment might exaggerate for the sake of irony, but I think you might be getting too close to applause-lights with it. You're saying (essentially) that it takes exceptional honesty to be willing to look at the evidence against your tribe's beliefs. That seems wrong. Complete and utter dogmatism isn't that common outside explicitly religious domains. People very frequently are honestly willing to look at the evidence against their wrong beliefs, and then they're honestly unconvinced by it, even if often it's because they misunderstood the evidence or failed to give it proper consideration. In fact, I feel certain that almost all neo-reactionaries think of themselves as willing to look at the evidence against their beliefs, as having done so many times, and as having vanquished that evidence.
