Now imagine someone stating that state regulations pertaining to authenticating food as kosher should be expanded. That is hey, my beef sausage is kosher (genuine/all right) so its unfair that these guys get to use that term but I don't.
The reaction from Jewish orgs will be to point out that the regulations on authentication were created based on the traditional definition, and suddenly having a ton of products using the same term but the more broad definition will create confusion for Jews, or anyone else wanting food manufactured using tradionally kosher methods.
Your example well illustrates the irony of what we are seeing.
In the "kosher" case, as you suggest, the Jewish groups would object to the definition of "kosher" being subsumed by the state, because they wish to preserve their traditional meanings. But for marriage, we see evangelicals demanding that the state subsume the definition of "marriage" so as to protect their traditions. I am continually puzzled that they fail to see the absurdity of this.
The proper thing for evangelicals to do, is to fight this out in the culture without attempting to involve the government. And you would think they would have the advantage there, because most people find their traditions to be comforting. Yet the evangelicals are steadily losing ground, most likely because of the
hateful methods that they use.
Just say no to McCain 2008; he abandoned principle when he caved on habeus corpus
