Of course the Talmud is not a book of jokes! But, like the Bible, it contains jokes that are obvious by their form such as (present case) "Two Gentiles and a Jew show up at a seance ...." It contains thousands of dense pages of all kinds of literature and should not be judged by a couple sentences.

Everything the Talmud says that is clearly about Jesus of Nazareth is relatively accurate (e.g. he died at Passover). However, the Talmud does have a lot of hatred for a man called Yeshu the Student, who lived in the 2nd century BC, and there is evidence that "Yeshu" became a stock character that later incorporated aspects of Jesus of Nazareth, and Yeshua ben Pappos, and others. Every historic passage about "Yeshu" is anachronistic with respect to Jesus. Therefore a joke passage about "Yeshu" is intended as a composite character and not as a specific person.

The encyclopedia of Jesus-hating is "Jews for Judaism" and other antimissionary orgs. They know they can't rile up Jesus-hating from the Talmud so they make up their own reasons.

If you want to prove the Talmud contains a couple satanic doctrines, I already told you, prove it from the incantations to devils and from the rejection of the voice from heaven. You don't know what's in the Talmud at large because you've only read a few sentences of it out of context.

Now listen carefully: The reason you've been shown only these sentences out of context is that when you go spouting them about half-cocked it benefits the Jews! It makes them look good to have people sincerely misquoting their text so that their opponents look like fools! If you want to trash the Talmud, do it right like those Talmud-haters who show up here occasionally, who say they hate the Talmud so much they're getting copies and reading it in context and having their families vet it just so that they understand it as it was meant! When you do this you'll be able to criticize it rightly, such as along the lines I indicate. Until then, you're not criticizing it at all, you're punching a tar baby that Br'er Fox laid out for you to get trapped in!
