I found it a bit unsettling that I, as a Gentile Christian, would be likened to Esau and Amalek. It seemed rather insulting, like calling Jews the seed of satan.
Well, considering that there are sects of Christianity which claim that the House of Judah is over and done with, and Christians have an exclusive birthright claim, somebody may have a point. If true, then the apostates are destined to sell their birthright to Jacob anyway, lol.
There are many schools of thought among Jews-- even among Orthodox Jews-- on many issues. My father, alav hashalom, was devoutly Orthodox but harshly criticized both Hassidim and Kabbalists for beliefs which he considered un-Jewish.
Yes, there are some anti-Christian statements in the Talmud, but understanding them requires a brief lecture on Talmud: The Talmud contains two types of material, halacha and hagaddah. Halacha is the rules-- is a particular animal kosher or non-kosher, is a particular act forbidden or permitted on the Sabbath, is killing someone under particular circumstances murder or self-defense-- and, on those issues, the Talmud comes to a conclusion: different opinions are debated, but eventually a consensus is reached or a vote taken, and a rule is set down. These rules are considered binding by Orthodox Jews, and of persuasive force by Conservative and, to a lesser extent, Reform Jews.
On matters of hagaddah, in contrast-- that is, matters of doctrine, history, folklore or other types of belief-- no conclusions are drawn in the Talmud; everything someone says is that one rabbi's opinion. Where two or more opinions conflict, all are stated, and none is authoritative.
The Talmud has a handful of anti-Christian (and more than a handful of anti-Roman) statements; all the anti-Christian remarks were made in times and places where the Jews were being persecuted by the Christian authorities. Some Jews today continue to quote these anti-Christian remarks; most do not hold any such beliefs.
I think the Romans came from The descendants of Japheth, I imagine that if the Romans were really Esau, that it would have been mentioned in Josephus. Not to mention that Latin is not a semitic language. I think what Libertarian Lurker wrote seems feasible.
