Today’s story is closely related to this concept. “We should therefore claim, in the name of tolerance, the right not to tolerate the intolerant,” Karl Popper wrote. “If we extend unlimited tolerance even to those who are intolerant, if we are not prepared to defend a tolerant society against the onslaught of the intolerant, then the tolerant will be destroyed, and tolerance with them.” In other words, if society is tolerant without any limits, the intolerant people will eventually destroy it. “Unlimited tolerance must lead to the disappearance of tolerance,” he wrote. In 1945, a philosopher named Karl Popper introduced a concept that he called the paradox of tolerance.
