Or alternatively, perhaps we can respect other peoples world views without judging them within our own limited set of cultural values.
Why wouldn't it last?
Why can't some members be incompatible with others?
Why must there be a framework to make judgements on others?
The United States is a good example (in a lot of ways) of successful multiculturalism (it's a bad example in some ways as well). But no official language, no restrictions on belief, the only consistant thing is a 'rule of law', is that what you mean by a framework for judging?
That's fine to not like it your self... but to condemn others... That seems more than just intolerant, that is verging on bigoted.
