> Is the difference meaningful? It’s proof of a value set so different from the community’s as to merit the same response: expulsion.
 

Is there a defined set of values that one must uphold, or at least believe in theoretically, to be a welcome member?

> We expel people for different values now?

Yes, that's what core values mean. If they're not embraced by everyone, they cease to be core.

If X11 tolerates developers who think piping data unseen to remote servers is okay, the project as a whole ceases to be trustworthy.

> I'm not Christian, should I be expelled?

From a listserv? No. From, like, a religious group? Maybe.
