Xenophobe's Paradox

As everyone well knows, hare and squirrel, while both furry forest animals, are rather different species. And, since they live in close proximity to one another, and are so different, they often have disputes. So they needed to find a way to get along. Each came up with a different solution.

Squirrel, for its part, decided it would mind its own business. So long as the hare did not try to tell it what to do, everything would be fine.

Hare, meanwhile, decided the best solution was to forbid all things squirrel. As long as nothing squirrel-like invaded hare-dom, there could be no conflict.
