I don't think we're going to agree if you think that "don't do that; you'll die!" is unconstructive hate speech and better left unsaid.

It's not hate speech, but definitely not constructive. And whether it's best left unsaid depends on the situation. Your street-crosser probably hasn't invested hours upon hours of time on researching and developing how they're going to run across the street.
