I saved a girl from getting raped

A couple days ago I was feeling really down on myself and even posted about it. I felt like my dad ruined my chances of finding love because of how he raised me. Me and my twin brother were both raised by my dad who's a marine war vet. He has PTSD and doe everything in his power to make sure me and my brother could protect ourselves and severely trained us. I'm talk sneaking up and attacking us with a loaded gun and our job was to disarm him. If we did we got to go to the movies. He taught us everything he knows and I know how to kill a full grown man 3x my size. My brother is gay and people underestimated him because of that so when 4 boys tried to jump him in high school he nearly killed them. Most guys don't like that about me. They want someone they can protect. I was feeling lonely and started to hate myself and wish I was weaker. My dad likes how we turned out. My brother is engaged to a man and in the military and I'm a physician... But I wanted someone to love me. I went out clubbing yesterday. Honestly in hope of meeting someone. I see a young girl around a bunch of guys. I then see someone slip some shit into her drink. She comes back and I walk over there and tell her not to drink that. She asked why and I said "Your possible rapist friends slip something in it". The dudes called me a liar. I told them to they're disgusting. The girl said she's leaving and I offered to walk her out. She thanked me. We were talking and I told her not to trust her drink with anyone. Then one of the dudes started telling at us calling us ugly bitches. I flipped him off. He ran up and grabbed my shoulder. I told that motherfucjer to take it off before I rip it off. He grabbed my arm and then I took him by the throat and slammed him into my car. Broke my whole damn window. Took a knife to his throat and told him to leave me alone. He was just sitting there wheezing and a guy ran over to see if we were okay. I said we're good. He and his sister saw the altercation. He then said "You're badass. That's hot". I guess I've realized that while most don't agree with how I was raised and may have thought some of my dad's.... Teaching... Was borderline abusive, I realized that I need to learn to be okay with the person I am and someone who likes me will be okay with that to. If my dad hadn't made me the person I am today who knows what would have happened to that girl. I'm not a damsel in destress and that's ok. I'm a protector.
