It's a matter of opinion

Last week the Conservative Jewish leaders voted to ease the ban on gay Rabbis and gave permission for same sex commitment ceremonies. Unlike Christianity, Judaism does not have a "Pope." Our religion is led by groups of Rabbis. More of a Democracy than anything else. No Rabbi leads all the Jews in the world in the sense of "do as I say, or..."

For those who are not familiar with Judaism as much - there are three main streams in Judaism (and one that is not as popular but does exist): Orthodox, Conservative and Reform (the fourth one is Humanistic Judaism, which I'm more aligned with). Within the Orthodox there are numerous sects that are defined by their founding Rabbi (typically of Eastern European descent back in the 18th century and going all the way back to before Christ). I'm over-simplifying it, so don't hold it against me. The Orthodox and Conservative are the main streams in Israel. The head Rabbi of Israel is Orthodox. Ultra Orthodox Judaism is the stricter of all. Ultra Orthodox Jews do not serve in the Israeli army. Conservaitve Jews serve.

The two other main streams - Conservative and Reform - are a product of the US & Germany (respectively) in the early 19th century. The Reform movement is not recognized in Israel. Meaning, their decisions and rulings do not have any impact on Jews living in Israel and are only relevant in the US.

In order to understand Conservative Judaism, one must understand Reform Judaism (which came earlier). Orthodox and Reform are on the two far ends of the Jewish faith. Conservative Judaism came about as an answer to Reform and an attempt to find the middle ground between the two extremes of Judaism.

One of the main differences between Reform and Orthodox is the definition of a Jew. Orthodox holds it by the mother - if the mother is Jewish, the child is Jewish. Reform includes the father - if the mother OR father is Jewish, the child is Jewish. The reason for the difference is quite interesting. Orthodox Judaism goes back in our history to the Rabbis of the 1st century, when the Greeks ruled over the Holy Land. The Greek soldiers would rape the Jewish women who became pregnant as a result. The Rabbis then were worried that all these newborn bastards with Jewish mothers would be lost to our people as they would not be considered Jewish. Due to the mass killing of Jews, and the fear that our people would be wiped off the face of the earth, they made a ruling that claimed that if the mother is Jewish, the child is Jewish - no matter who fathered the child (whether a product of rape, adultery, etc.). The reasoning behind this ruling - you could always tell who the mother is, you couldn't tell who the father was. Reform Judaism came along and said that in modern life and with the assimilation of Jews into other faiths, we're losing too many potential Jews due to interfaith marriages (a Jewish father to a non-Jewish mother). So they made a ruling that claimed that if the father is Jewish the child is Jewish. Of course in modern science it's easy to tell who the father is, so this ruling was just advancing with science.

One almost expects only two ends to any discussion in Judaism (e.g. You're either defined a Jew by the mother or both). But here comes a very common belief about Jews that many gentiles find amusing:

If you have two Jews in a room, you'll have three opinions.

For those who think this impossible, funny, unrealistic, stupid, I want to stress that it is absolutely true and is an integral part of being a Jew. We hold the concept of discourse and discussion in high regard and it's essential to play the devil's advocate in any disagreement. It's part of our upbringing and our way of thinking. It goes back to the Talmud scholars of the 1st century and it remained in our teachings since.

Case and Point: read the article about Conservative Leaders voting to ease the ban on gay Rabbis. I bring to you the quote from the article:

Four of the law committee's 25 members resigned in protest of the decision.
It takes the votes of six panel members to declare an answer to be valid.
Thirteen members voted in favor of allowing gay ordination and same-sex ceremonies, and 13 voted against — meaning that at least one rabbi voted for both positions.
