> I think a good CoC should be specific enough that it is actively repulsive to some people. And frankly, the more people who are repulsed by it the better.

I'd say that in this case, the best version is the one that names explicitly people who are allowed and others need not apply.

But then again... It's actually an interesting train of thought. How should I repulse, in one simple sentence, both right-wing and left-wing nutsoes? How can I make sure the result of this repellent is not an empty set?

But then again, maybe only the nuttiest ones should be repelled, and the rest will read the room...
