Intolerance Paralax

I've often thought about this problem: how do tolerant people tolerate the intolerant people. It was clear to me that the tolerant would always, in the long run, lose to the intolerant, unless they themselves become intolerant to the intolerant. If you get what I'm trying to say!

And if you don't, there's actually a term for this: Paradox of tolerance, first described by Karl Popper and explained much more clearly on WikiPedia.
