Nothing to do with the Kushners, but an interesting comment I saw on Reddit, somewhat related to this thread:
"The liberal Jews say that they are promoting Judaism, but after it gets filtered through their BS, there is nothing left.
Belief in one God isn't even a prerequisite for their Judaism anymore.
Belief in God isn't even a prerequisite for their Judaism.
The Judaism they practice is no different than a Native American trying to get back to his roots by wearing an Indian costume from the costume shop.
They don't answer to God. They answer to their own intuition.
If you tell them, why is it wrong to kill someone, they won't say because God says so. They'll say because they feel it is. But where does that feeling come from? And what makes their feeling worth more than a killer who feels it's right to do so?"
