This is important: the leadership of the The United Synagogue of Conservative Judaism has issued a statement on the proposed Marriage Amendment. This is the faith in which I was raised. Despite the term "family values" having been a euphemism for "intolerance" for some time now, it so happens that the views of all of my immediate family (parents, brother, uncle, grandparents) with whom I've spoken on politics and religion pretty well correspond to this statement.
In other words,
"The United Synagogue of Conservative Judaism views the application of equality as a standard which cannot be eroded by any other determinant, race, religion or history. Our Faith Members are not unfamiliar with discrimination and worse.....we will reject it, however garbed and rationalized, will fight for equality and will be determined in our stance by genuine equality, .neither discrimination per se nor discrimination garbed in the dress of double standards."
I've only copied the first paragraph here; go to the link above to see the rest. I recognize that a good chunk of it translates to "Quit poaching on our turf!" and that saying that the government has no business restricting marriage among consenting adult citizens is not the same as saying that this branch of Judaism supports this particular flavor of marriage. Nonetheless, I'm very pleased that they agree with me that being Jewish requires us to commit to rejecting discrimination and fighting for equality for all people.
