The Paradox of Tolerance You can't keep sheep and wolves in the same barn. "The paradox of tolerance states that if a society's practice of tolerance is inclusive of the intolerant, intolerance will ultimately dominate, eliminating the tolerant and the practice of tolerance with them. Karl Popper describes the paradox as arising from the fact that, in order to maintain a tolerant society, the society must retain the right to be intolerant of intolerance." https://en.wikipedia.org/wiki/Paradox_of_tolerance
