Even athiestic historians don't dispute that Christ WAS an actual historical figure. Oh, sure, I'll bet you can find a couple crackpots out there to argue the point, but then again, you can for almost anything.
The most significant person and events upon this earth are certainly not a myth. If Christ DID exist, then you are faced with several questions, such as WHO was He? What are the implications? Etc. You have simply chosen the easiest way to avoid all that by pretending that He never existed.
I'm not pretending at all. As I said, up until recently I believed there was a Jesus of Nazareth. I'm not so sure now. At any rate, he was not god.
