One of the members of the Frum Skeptics Group was complaining about davening and how we should take large parts of it out of Jewish practice. He was saying,
"Endless hours of davening. You ever see the mincha factory on avenue L? Rabbis who insist on 3 hours davening on shabbos. Stupid superstition. Ah whats the use, it is what it is."
There's no harm in davening mincha. For those who find meaning in it, good for them. I hardly ever daven mincha, but why take it away from those who do?
And for Shabbos morning, I don't usually come until the middle of Torah reading. That works for me, other people like to come in at 8am. That's fine too.
Would you take that all out of Judaism just because you don't consider it meaningful to you? Judaism is for all the Jews, not just for the skeptical ones. I'd prefer to see a pluralistic Judaism rather than one that serves just one segment.
