The people who are absolutely certain that everything they think they know is absolutely correct are the hardest to convince that they could be wrong.

We have an acquaintance who is absolutely certain that the Holocaust never happened, Hitler's intent was misunderstood, that there was no moon landing, 9-11 was an inside job and much more that I cannot believe. He cites sources that sound good but really are just people writing on the internet. He has a 4 year college degree.

We hold our breath whenever he is around hoping his wild beliefs will never come out. He sees us as the stubborn people who will not see the light.
