Again, there are many sites out there that do this story justice. I just wanted to make the point that he doesn't believe that there is enough evidence to convince him about the holocaust.
Amazing. Despite the overwhelming evidence: eyewitness accounts, confessions of Nazis, graves. If it wasn't so insulting, it would be darkly funny. This is, quite possibly, someone I wouldn't even attempt to convince with an evolution argument. (Some people are just too stupid.)
But people are allowed their opinions, and I would strongly defend that right. I am appalled that the Pope - the highest christian authority on the planet- seems to think it is OK to welcome him back to the church! It really does send the wrong message I think.
I could argue that there is considerably less evidence for the existence of the biblical holy Jesus! But that would probably just annoy people... ;-)
