This is a very good clarification. Something can be dangerous without actually being a threat, and in fact the response here has been what I'd expect for an indirect danger - I don't know about anyone else, but I don't usually stick around to try to educate someone who's actually threatening me, or causing me to be in immediate danger.

Think of it as the difference between teaching people to hotwire cars, and actually stealing them - the former might not actually harm the car owners in question, but they're unlikely to think kindly of someone who does it.
