These examples just show that 100% tolerance, or tolerance of all ideas, equally, is a fairly tale proposition, not practical, and not conducive to well-functioning society. I like the concept of fuzzy-tolerance: try to understand where the accoster is coming from. Maybe some of his ideas have merit, while clearly others do not. Society should be in a constant tug-of-war, or re-negotiation, between tolerance of some ideas and intolerance of other ideas. The same thing happens, on a smaller scale, in your own mind.
