Why do some Christians believe that "messianic Jews" are the real Jews and real Jews are not real Jews?

You are STILL A JEW and they, due to their unbelief, are not." The "they" which this person refers to are the approximately 13 million Jewish people of all branches (Orthodox, Conservative, Reform, reconstructionist, etc) and the "unbelief" she refers to is the fact that Jews do not believe in Jesus. This answerer claims that the "messianic" Jews" (Christians who call themselves Jews) are the real Jews and the actual real Jews are not Jews. Is this person just plain crazy or just antisemitic or both?

Jews and Jews alone have the right to determine their own identity and not Christians, whether they are honest and call themselves Christians or dishonest and call themselves "messianic Jews". Do you think the thoughts of Hindus should determine what constitutes Christianity? How about Muslims, should they be the ones who determine what Christianity is? No? How about if Hindus or Muslims just called themselves Christians but continued with their Hindu or Muslim beliefs, then would it be alright for them to dictate what Christianity is? That is what the Christians who call themselves Jews are doing--claiming that THEIR beliefs define Judaism, not the beliefs of real Jews. That is what is happening.

I can IF IF IF too, and because you seem to think that if if ifing makes for a valid, logical argument how about this: IF IF IF it was discovered that Moe of the three stooges was the messiah, would you give up your belief in Jesus and instead worship Moe? Well, would you? Huh? How about it? NO? Why not? Do you see how RIDICULOUS that statement of yours is?
