Fine, guys... you guys sit around and hold hands with gang members, and show them you can walk off from their violence. I'm sure they will follow your good example, and give up the gangster lifestyle.
What probably happened, for real, is that they had something else to do rather than kick Speedy's a$$ at the time. Along with all the training I've done, which is another sore spot with you guys, I also worked undercover for two years. There isn't much I haven't seen or been around when it was going down... both from gangs, drug dealers, and every other kind of scumbag out there. All they respect is the guy with the biggest gun... and turning around on them only offers them a bigger target.
I avoid violence at every opportunity, but I'm smart enough to know when it's going to be necessary, and I don't attribute that to martial arts training, but to living in the real world. The ability to use my training is where I have an advantage, and there are lots of times when I could unload on somebody but don't.
If you keep cruising around in gang territory, you'll eventually "get in touch" with them. If you're lucky, you'll live to go somewhere else... if not, don't say I didn't warn you. I'm just not going to nominate you for sainthood simply because you walk away from a fight. You might have only lived to fight another day because they didn't have a gun with them. The answer is to get out of the area where that situation will occur... much less where it is the "regular" occurance.
Like I said before, adults make those kinds of decisions. Bravery and walking away will get you killed, and a brave dead guy is just as dead. I grew up around gangs, and they don't respect your walking away, even if they don't take any action this time.
They'll be around... and they have a shot at you any time that you are.
