"Have you considered men do know the fear because they have put themselves in that situation and gotten the living shit beaten out of them for doing it?"

NO - you don't know the fear. You are describing a completely different fear. You are describing the result of a deliberate action on your part - intervening. We have the fear when we go about our daily lives. We don't even get to make decisions about our fear; it's completely up to men. Do you understand that?

And - "What's in it for him?" - why does everything to do with women have to be transactional? (Rhetorical question.)
