And That's Their Red Line?

Non-religious and religious Jews in North America define Judaism quite differently.  For many of our non-religious brethren, Judaism is a religion like Chrisianity, something you practice rituals from when you attend "temple" on Saturdays and when holidays roll by but not a fundamental party of one's identity.  For others, it's an ethnic identity like Italians being Italian.
As a result North America has proven a fertile ground for groups such as Reform and Conservativism which present a Judaism that claims to allow a person to be a good Jew in the absence of binding obedience to Torah and halacha.  And then there's the Reconstructionists.
Like Humanist Judaism, Reconstructionist Judaism can only really call it that because Moshe Rabeinu, a"h, did not take out a binding copyright on the word "Judaism" the day after bringing the Torah down from Sinai.  As anyone familiar with the movement knows, Reconstructionists reject pretty much about every fundamental belief that the Torah requires a Jew to have to be considered in good standing.  It really is a different religion with secular liberalism as its guiding role, not Jewish values.  As a result one should not be surprised to find their "rabbis" espousing values antithetical to Torah.
What I always find curious about groups like this is their red lines.  One you've dumped the Torah as an external, unyielding standard, why does the answer to any question have to "no"?  Why are there suddenly any limits other than those things forbidden by law in the surrounding society?
And that's why I was surprised to read this on line:

Seven rabbis have quit the Reconstructionist movement in the wake of an announced policy that allows rabbis to marry non-Jewish partners.
Several synagogues are also discussing potential responses to the new policy, the Forward reported over the weekend.
The policy was announced in September after the faculty of the Reconstructionist Rabbinical College voted that having a non-Jewish partner would no longer bar qualified applicants from admission to the rabbinical college or from graduating as rabbis.
According to the Forward, one of the seven rabbis who has withdrawn from the movement is Rabbi Reba Carmel, who serves at a nondenominational synagogue in Warrington, Pennsylvania. She told the Forward that the policy allowing intermarried rabbis is “detrimental to the Jewish people in America.”

Really?  They've dumped Shabbos, kashrus, and taharas hamishpacha along with approving of lifestyles the Torah strictly disapproves of.  That's all okay for a Reconstructionist "rabbi" but to be intermarried is suddenly assur?  How does one justify this selectivity?  Encouraging assimilation is fine but living it to its logical conclusion isn't?
Perhaps this is another reason the Torah observant don't take the non-observant movements seriously.  When you have a"Let's make it up as we go along" method it's kind of hard to.
