More importantly, I agree with parent that expressing views is something else than actively exploiting someone or using violence. Words != violence. Tolerance is being able to co-exist, work with and even be friends with people we disagree with. And, yes, that include people we think are intolerant (or that will be the excuse not to do the hard thing and engage in debate).
Open debate is a good thing, and it was hard won. Let's not throw it away so quickly.
