Can't speak for the OP, but as a (maybe possibly somewhat arrogant) man, the most I have ever mustered towards unwanted people bothering me was cold, superficial politeness, just barely enough that they can't say I'm wronging them. Not sure if that counts as being "nice" under intimidation.

In Europe? I suppose it's possible in some pathological neighborhoods but I would be surprised to hear it's a common occurrence. But then, I guess, once per lifetime is dangerous enough, as you say.
