oomis is not suggesting that she is the only one that is right.
She is saying that people judge others on where they daven, how they daven and which minchagim they follow – when in fact, everyone is a Jew, even with different customs. We all read the same Torah, celebrate the same Yomtovim and have the same forefathers. (oomis – I think that is what you meant – that is how I understood it).
Aries – as usual, I agree with you completely.
