Even in an emasculated society there are countless testosterone filled men who will not hesitate to snap your neck.
If the shit hit the fan could you defend yourself or your family against a man the same size as you? Against a man bigger than you?
If a man bigger and stronger than yourself slapped you in the face in front of your wife, girlfriend, or kids would you take him out?
Or would you hang your head in shame?
Walking away is always the best option, but what if it isn't an option? 99 times out of 100 a bar-room altercation will not come to blows, but that 1 time it does won't end up so well for you if you get beat up.
If another man strikes you you strike back. Even if you do get beat up, when you go down you go down fighting.
The late, great Jack LaLanne tells a story about being a younger man, eating in a diner and 3 punks come in and start making fun of him, calling him “muscles” and ridiculing him.
Jack took the 3 punks into the parking lot and dealt with each of them and went back into the diner to finish his meal. All the patrons in the diner thanked him and clapped for him.
There is a difference in walking away from a silly fight and being a coward who has no pride.
Steps to learning to defend yourself:
Get into shape: a frail body isn't defending anything. A man in good shape is more intimidating to someone who wants to pick an easy fight.
Learn some form of defense: could be boxing, mixed martial arts, Brazilian jiu-jitstu, a self defense class, or you could have a friend teach you some moves. Watch some self-defense videos if you have no other options. The confidence alone from knowing you can hold your own and defend yourself is worth more than money. Walking down the street I am comfortable in the fact that if a bigger man than myself gave me some trouble I can hold my own. I may take a few licks but I'll give just as good as I got.
Talk yourself out of the fight: If a fight can be avoided, it should be avoided. You never know who's carrying a knife or a gun, or if he has friends waiting in the distance.
Position yourself for easy defense: If a man is getting in your space you never keep your hands in your pocket, you keep them up to defend your face. Don't make an overt boxing stance, you can pretend to be scratching your chin or something like that. Your hands always need to be ready to act. When the fight starts always protect your face with your forearms, hold your arms up at a 90% angle, thumbs facing your head.
If it comes to blows: Move quickly. Get your hits in as fast as you can, subdue him as fast as you can, and get away as fast as you can. A hard punch to the throat will take him out. A rear-naked choke will take him out. A hard kick to the knee will take him out. A hard knee to his face will take him out. If you're trading blow for blow you aim for the jaw. Always keep your hands up in front of your face to protect yourself.
Fight dirty if it's life or death: If you're fighting for your life all rules of combat decency evaporate. This is where you kick the groin, bite the nose, poke the eyes, any severe damage you can do.
Never pick a fight: Only finish one if it is necessary. A man has no business not knowing how to stand up and fight for himself.
