Everyone knows that "tough guy" now days... It's annoying. All-talk punks that nut up when faced with a real aggressor. There are real predators all over the place. LoL, but, they don't advertise. Bring fists? They brought a knife... Bring a knife? they brought a gun... Not scared of guns? They apologize and ask to make it right... In general (and in my opinion) people are much more aggressive, and soft, than 20 years ago. Too much PPV MMA, and too many chuck noris movies and cops episodes... Fighting is easy. Winning a fight is simple, and losing a fight (but still bowing up) is even more simple. Defending yours ... your person and the loved ones that can't always defend themselves, with knowledge, and the wherewithal to back down when the confrontation has been resolved, is a lot more difficult. Especially without crossing the line.
