Maybe that exemplifies the kind of hostility that was being
referred to.

I think it's accepted by everyone that the example is or might
be impossible, isn't it?

Is that situation impossible because it isn't possible to supply
a set of rankings for it? Of course, aside from that, of itself,
it the fact that no one ranks A over B doesn't meant that A can't
have a strong beatpath to B. And the fact that someone ranks B over
A doesn't mean that B has a strong beatpath to A. But maybe it's
