Surprise! I belong to a Reform synagogue. Doesn't sound anywhere near as liberal as what you describe, though. I live in an area with a very sparse Jewish population, so there really isn't any alternative. Our membership ranges from very Reform to 'Conservadox'. It is possible to be fairly observant in a Reform congregation, it just requires a little more self-study. If your present congregation isn't doing it for you, I hope you'll explore some alternatives.
Well, the thing is, I no longer believe in God, so I think it's kinda pointless for me to go to a real synagogue (or one at least somewhat religious). Maybe I'll believe in God when I get older (maybe there's hope, lol).
