Well I'll assume you never read the talmud so here goes: It is not a sacred book the way the Torah is to the jews (which comprises the 5 first books of the bible). The Talmud is mostly a collection of some law (Mishnah) mixed with rabinic debates (where the messed up stuff shows up), Judaism is by nature very open to debate and questioning and challenging the dominant narrative is not only allowed but actively celebrated (the "two jews, three opinions" joke is very much deserved), very different from Christianity and Islam. That being said, there is certainly no shortage of horrible and disturbing stuff in the talmud, but those represent the opinions of specific rabbis, many times written while jews were being prosecuted by Christians. The fact that stuff is written in there doesn't imply it's the dominant view amongst jews, also a lot of them ignore it altogether and follow only the Torah.
