Jews explain why Christ is a failed messiah; Christians, offer your rebuttal
Back when I was Muslim, part of our apologetics was being able to prove how Islam came after and abrogated Christianity and Judaism. Now, the main (but not only) argument I had based myself on were in regards to the horrible textual history of both the Old Testament and the New Testament, as opposed to the Qur'an, of which even discovered "destroyed" copies had mainly dialectical differences, and both Sunni and Shi'a groups almost universally agreed on one copy of the text.
Anywho, from my studies, one thing that always did bother me was that if I had been a Christian, it seemed I had little to no way of proving Christianity to a Jew. Since Islam had the easy (if not intellectually dirty) way of stating that anything that disagreed with it scripturally was obviously a human distortion, I didn't have to deal with it. But Jesus, by all Jewish account, was a failed messiah, and his apostles (who were not trained in scholarship) misinterpreted the Torah in grossest of fashions. It seems the anti-intellectualism of modern evangelicals can take inspiration from the very first uneducated Jews who formed the highly eccentric and bizarre Christian world view.
Here are two links for you:

A contemporary Jewish criticism of Christianity: http://www.jewsforjudaism.org/index.php?option=com_content&view=category&layout=blog&id=72&Itemid=507
I had read a bit of the former work back when I was a Muslim, but the latter articles are a bit after my "giving a shit" stage. I'd love to see you counteract these, which I imagine will be hard considering few to no Christians are educated in Jewish tradition at all, let alone on the level of rabbinical scholarship. Well, to be fair, the first work was written by a Karaite, the Karaite movement being an anti-rabbinical movement in Judaism that was pretty popular in the medieval Middle East, and is making somewhat of a comeback today.
Anyway, give it your best shot.
