Person Who Doesn't Believe in the Holocaust

If somebody told me that they didn't believe in the Holocaust I would first call them ignorant. I think that is probably one of the dumbest things a person could possibly say, since the holocaust is one of the most well documented events in history. What would be there response when shown a picture of all the skeletons, hair or pictures of crippled people? It is also well documented all of the concentration and extermination camps along with the ghettos and major massacre sites. The pictures and videos of the time alone should be enough to shoot down anybody not believing in the holocaust. Nobody is that thin and crippled if they aren't put through torture like victims of the holocaust were put through. There is endless proof, pictures, videos, journals, documents and the actual remains of the camps. To say the holocaust didn't happen, is the same as saying you are not an educated person.
