I saw a production of Fiddler maybe 15 years ago, but from what I remember its message was something like “don’t let tradition stand in the way of love”. My family has found plenty of ways to honor tradition while reshaping those traditions to also honor our values and views; our Seder Haggadah is full of taped-in pages like modern plagues and Miriam’s Cup, and crossed-out or edited sections like “the wicked child”. But a legal contract/institution is a bit more involved to edit and update…
"But here, in our little village of Anatevka, you might say every one of us is a fiddler on the roof trying to scratch out a pleasant, simple tune without breaking his neck. It isn't easy. You may ask 'Why do we stay up there if it's so dangerous?' Well, we stay because Anatevka is our home. And how do we keep our balance? That I can tell you in one word: tradition!"
