I step forward too. I can't turn away. I was really scarred by the well known incident of a woman's violent murder which is told to illustrate a certain mob mentality. i.e. People generally think it's none of their business or that someone else will intervene when someone is in distress. I was at home one night when I lived in London and witnessed a violent argument between a couple where the guy, after jostling his girlfriend around, pushed her into his car and grabbed a crowbar from the back of his car unbeknownst to her. I ran down my stairs so quick and ran after the car to help her. I had called the police when I saw him initially assaulting her and they got there right on time.
I don't know what comes over me but I've had several times in my life where I have confronted scary situations. I think it's the decent human thing to do rather than type related of course. It probably just comes as a bit of a shock that seemingly placid infjs can be so fearless. I guess we do have 'the Protector' as a moniker though, lol.
