Firstly taking a progressive Jewish temple for an old man's funeral and using a female rabbi is very unlikely. In fact the elderly more often than not openly don't visit temple where a woman is the rabbi, because it is unorthodox. As for the "rabbi" stating there is no heaven nor hell, she obviously doesn't know about Sheol or Paradise that the entire old testament talks about.
Next up there was Christianity. The idea of original sin is Calvinistic in nature and almost no churches with "pastors" (like in this show, also considering a homosexual runs the childrens choir, the church is definitely charismatic) preach this, apart from that, the reason for baptism is also not at all connected with the "original sin" theory.
I think if everyone in the world just took some effort to understand other's beliefs we wouldn't think less of anyone we don't understand.
