Well, if the conversation is important at all, maybe it would have been better if the OP simply asked Jews; instead of posting a propagandistic video that starts with the assumption that there is ‘One Simple Reason’ and ‘Jews Are Wrong’.
Jesus would never have developed his philosophy at all, if he hadn’t grown out of a much older and very deep one. Instead of trying to find superficial ‘reasons’ why many Jews didn’t accept Christ, maybe it would be enlightening to actually learn something about Judaism and why it is sufficient to those who hold it sacred.
Exactly where do you get power and authority to speak for Christ. Stick to the Scripture... people are given the 'right' to choose what path they will take. Christ is the same yesterday, today, and will be forever ... He was God with us, regardless of what any other religions claim.
