Question: Why are humanists so intolerant and so easily offended?

Why is it so easy to wind up a humanist? Mostly because of stuff like you’ve written here, i.e. ‘why don’t they have patience with believers?’ We have used most of our patience up by the time we finish listening to your whole question/tirade—or anyone’s rant about how important their imaginary universe is. You do realize that your question could be reversed—just replace ‘humanist’ with ‘theist’, and ‘faith’ with ‘reason’—and you will find yourself being asked the same offensive question you are asking us.
