Yes they are. I have witnessed stuff like that on a couple of ocasions. The way I see it guys like that only give a refined gentleman with an imposing phisique have a chance to shine.
3 short stories:
I was on an almost empty train. In the same car there was a cute girl and a trio of "gangsta" ghetto scum. One of them grabbed the girls ass. She complained. All three started calling her names. By that time I was already behind them. The first guy made a move to touch the girl again, I held his wrist on a lock behind his back using him as a kind of human shield. One of the other guys moved towards me and I shoved a taser in his face (I worked for the police and had just got out of work) and said "Touch her again and you will be jerking off with your elbows from now on". A few minutes later we arrived at the next station and I kindly escorted them out flashing my police laminate. Good thing they did not notice I was just an economic activities inspector and not an actual cop
I was working security on a concert. A drunk guy started feeling up a girl there. She tried to escape but he was phisically restraining her. I approached the guy, put him on a chicken wing lock and delivered him to two colegues to escort him out.
I was at a club with some friends. Some dude tried to force kiss a girl. I said "Hey, pal, the lady said no". He: "What are you going to do about it?" "Take you outside and fuck you up so bad you will eat through a straw for the next month." By that time the rest of my friends (big guys for the most part) were already surounding him and the dude backed down. I also knew the bouncers there so it was pretty much a done deal.
And yes, I eventually date/hanged out/became friends with all three.
