We all need to be a little more mature about this. There's simply no way to synthesize all of Orthodox Judaism into one big happy family...Read the whole thing.
Why is this so difficult? It's because we frum Jews have been socialized against making independent religious decisions. The mantra of Orthodoxy today is "Ask Your Local Orthodox Rabbi." And while that's usually a good idea, it's gotten to the point where we are afraid to take any positions ourselves...
Choice is scary to the frum. It's much easier to abdicate this need to choose by pretending there aren't any disagreements in the first place.
I think this ties in perfectly with a series continued by DAG from yesterday, The Problem With Charedim. If instead of people judging one another by certain differences in certain psak, people would actually respect the opinions of different groups, we would be far, far better off.
