@bmacDonald94 I still find it weird that an intelligent man like Popper makes tolerance so complicated. We don't need to claim anything - tolerance, by its very nature, not only allows but demands we do not tolerate the intolerant.
Tolerance is a peace treaty, not a suicide pact, and thus only extends to those willing to abide by it, which naturally excludes the intolerant.
