I am not a Man

I have been emasculated. My manhood has been removed.
Let me explain...
Yesterday on the train (this train is becoming regular feature!) there were two drunk-and-disorderlies being, well, drunk and disorderly. They were pretty close to where I was, and one of the passengers had already crossed verbal swords with them. I had already started preparing myself to unleash my "crouching tiger, hidden dragon" on them.
Long story short, the rail staff took them off the train. No action.
Late on I told my significant other about the ruckus. What did she say? Not "what would you have done", no. She said I mustn't get involved, because I'm not "prepared" for it. Shlop! Is that my manhood lying on the ground? If in her eyes I'm not prepared to deal with drunk-and-disorderlies, what does that say about her view of my ability to protect her from a real threat? I might as well just hire a personal bodyguard to keep us safe.
Say what you like about the modern world no longer requiring men to fight off threats to his family, or hunting for food. But, as any man worth his testosterone will tell you, there is a deep-seated need to know that you can protect your family, and to know that they trust you can.
My tactic for self-defense has always been "hit first, hit fast, and keep on hitting!" I will not start a fight, but you better believe that I will finish it if you bring it to me. So, could I have dealt with the drunk-and-disorderlies on the train? I am confident I could have. I may not have done any martial arts training for a couple of years, but I still have the knowledge, and I still have the attributes required: strength, speed, timing. I know about angles of attack and vectors. I know I can.
Now I just need a way to convince the little woman...
