1-There's no kidnappings and robberies in America?
2- That's my point, how many people can carry a gun 24/7? go it now? 
3- Old ladies carrying a gun to defend herself ? she is right, but a man relaying on one all the time? c'mon man up.
4- Renzo's place in NY its full of women learning BJJ.
See im not against guns, my point is since most people can not carry a gun all the time.
What are you going to do to protect yourself?
Most of parents in Brazil put their daughters to learn some kind of self defense.
1. Yes, 95% of which are pedofiles.
2. Everyone I know that has a carry permit has their gun on them the 90%of the time. Most also carry a knife as I do.
3. It's not about being a coward, it's about being prepared. The criminals are cowards and will almost ALWAYS have a weapon. Just like all the "Gangsters" these days..to scared to take an ass whooping. So if you see a homied out, hippity hopping, 5'6" 134lbs "gangster" who is talking mad shit to you when and if you visit this great free country, walk because there is a reason he is that brave and it's probably tucked in the back of his waist and your krav / JuJitsu won't get withing 10 ft of him before he "bust a cap" in your ass.
You assume that everyone you meet in a confrontation isn't armed..maybe in Brazil no, but here in the US most are in some form.
I agree that learning to fight is a valuable skill but what we are arguing is a fighing skill that is REALISTIC. Krav may be "deadly" but I have yet to see ANYONE that claims a martial art stick to it when engages in an actual street fight. At first they do and then after a few well placed face shots they "break form" and just rush the guy punching wildly..usually falling to the ground where they get topped and pounded into the sidewalk.
Just like the Kiai Master video above..everyone claims its deadly and may even shoot a video showing the "invisible black touch of death" move or whatever but when it comes to the real world, a well placed hit to the face ends the fight in 10 seconds.
Make sense? Hard to triple roundhouse, krav poke me in the eye after the initial 3-5 second punching barage that has swollen your eyes, cut your eyebrow, broken your nose or ALL of the above...assuming I haven't knocked his ass out. Though I have to admit, if the guy was a real douche I have been known to punch him in the face a couple of times after knocking him out just so when he wakes up he has something to look at in the mirror for a couple of weeks and remind him that he isn't as tough as he thought he was and needs to take more KravjudoTai-whatever lessons.
